Marriott Bonvoy members who need points for a near-term award stay have a dated purchase window, not an open-ended buy-anytime plan. The current promotion runs through September 9, 2026, and can cut the cost of purchased points to about 0.83 cents each when the top bonus tier is available.
The traveler decision is narrow. Log in, confirm your personal bonus tier, price the nights you actually intend to book, and buy only if the award math still works after taxes and fees.
Specialist coverage such as One Mile at a Time reporting on the Marriott Bonvoy buy-points window through September 9 and AwardWallet’s summary of the same up-to-50-percent purchase bonus both place the offer between early August and 11:59 p.m. ET on September 9, 2026. The terms in those reports describe a targeted promotion with tiered bonuses and a temporary higher annual purchase cap.
- Window: Buy by 11:59 p.m. ET on September 9, 2026, for the current bonus campaign.
- Top bonus: Up to 50 percent on larger purchases when your account is targeted for that tier.
- Floor cost: About 0.83 cents per point after a full 50 percent bonus, before any taxes.
- Cap: Reports show a temporary annual purchase limit up to 200,000 points for this offer.
- First step: Log in on Marriott’s purchase page and read the bonus your account actually shows.
What the September 9 buy-points window offers
Marriott periodically sells Bonvoy points with a limited bonus. This round is useful because it pairs a firm end date with a higher bonus ceiling than the ordinary purchase rate.
Reporting on the live campaign describes a common pattern: a lower bonus on smaller buys and a higher bonus once a purchase reaches a larger threshold, often around 40,000 points in one transaction for the top tier. Some members see 40 percent as their best offer. Others see 50 percent.
That targeting difference is the most important traveler fact. Two people can open the same purchase page and see different percentages. Screenshots from friends are not proof of your rate.
The temporary annual purchase limit increase, reported at up to 200,000 points during the promo, matters for people topping up a big multi-night award. It does not create a reason to stockpile points without a booking plan.
Purchased points are generally non-refundable. Once the card is charged, the decision is hard to reverse, so treat the purchase as a cash outlay against a specific stay rather than a speculative investment.
Bonus points from a purchase do not behave like elite-qualifying nights. They help with award inventory, not with status math.
How to decide whether the 0.83-cent rate is worth it
Start with a real stay. Open the Marriott app or site, search the exact hotel and dates you want, and note the points price and cash price side by side. Then divide the cash room rate by the points price to estimate cents per point for that night.
If the stay values points near or above one cent each and your purchase cost is about 0.83 cents after bonus, the buy can be rational for a short window. If the stay values points at 0.5 cents, the same purchase is a loss even with a 50 percent bonus.
Taxes, resort fees, and parking still matter. An award booking can still leave cash fees on the folio. Include those fees when you compare buy-points against a fully cash rate.
Fifth-night-free award benefits and free-night certificates change the math. A certificate that already covers the expensive night may make a top-up purchase unnecessary. Run the booking both ways before you buy.
Transfer partners and credit-card earn paths can be cheaper than buying. If you can finish a welcome-bonus spend or transfer from a transferable bank currency at a better effective rate, do that first.
Travelers who redeem Bonvoy for hotel nights near theme parks or cruise embarkations should keep the stay plan concrete. Guides such as Deep Arrival’s list of hotels near Port Canaveral help connect a points purchase to an actual embarkation week instead of a vague future trip.
Families planning California park weeks can do the same with Deep Arrival’s guide to family-friendly hotels near Disneyland. Buy only the points needed for the shortlist of hotels that still show award space.
How to complete a purchase without waste
Log into the Marriott Honors purchase flow with the same account that will redeem the nights. Confirm the on-screen bonus percentage before you enter a card.
Buy in the fewest transactions that still hit the better bonus tier. Splitting into many tiny buys can leave you in a weaker bonus band if the rules require a minimum size for the top rate.
Wait for points to post before you lock an award that depends on the full balance. Specialist reports commonly note posting within a short window after purchase, but inventory can change while you wait.
If you are close to the annual cap, calculate remaining headroom before you submit. Hitting the cap mid-trip planning is a worse outcome than buying a day earlier inside the promo.
Keep a written note of the purchase amount, bonus percentage, and target hotel. That note helps if customer service later needs a receipt or if you compare future sales against this one.
Do not buy points solely because the end date is near. A deadline is a forcing function only when the award math already works.
What is still open or account-specific
Marriott can change or end promotions, and targeted offers can differ by member. The public specialist terms summarized here are a planning baseline, not a personal guarantee.
Some accounts may see only a 40 percent top tier. Others may see different minimums for the best rate. Always prefer the numbers shown after login.
Award pricing is dynamic. A hotel that looks efficient today can reprice tomorrow, so recheck the stay after points post and before you celebrate the purchase.
Taxes and local rules for Canadian or other non-U.S. residents can add charges on the purchase itself. Read the purchase page fine print for your billing country.
| If you… | What to do |
|---|---|
| Already see award space for a near-term stay | Price cash versus points, then buy only the points needed for that booking before September 9. |
| Do not have dates or a hotel shortlist | Skip the purchase. A deadline is not a reason to stockpile non-refundable points. |
| See only a 40 percent bonus after login | Recalculate at the weaker rate. Do not assume a friend's 50 percent offer applies to you. |
| Can finish a card bonus or bank transfer instead | Use the cheaper earn path first, then top up only any remaining gap. |
| Need many nights near a park or cruise port | Confirm award inventory first, then buy in one or two transactions that hit the best tier. |
- Deadline: Complete any purchase by 11:59 p.m. ET on September 9, 2026.
- Login first: Trust only the bonus percentage shown on your account.
- Stay math: Compare cash and points prices for real dates before buying.
- Cap: Watch the temporary higher annual purchase limit if you need a large top-up.
- No refund: Treat purchased points as final once the charge clears.
This is a bounded loyalty sale with a hard September 9 cutover. Use it to fund a priced award stay, not to invent demand for points you cannot spend well.
When does the Marriott Bonvoy buy-points bonus end?
Specialist reports place the current campaign through 11:59 p.m. ET on September 9, 2026. Confirm the live end time on the purchase page after login.
Is every member offered 50 percent?
No. The promotion is widely described as targeted. Some members see 50 percent on larger buys, while others see lower top tiers such as 40 percent.
What is the effective cost after a 50 percent bonus?
At the common retail buy rate with a full 50 percent bonus, purchased points work out to about 0.83 cents each before any taxes on the purchase.
Should I buy points without a hotel booking plan?
Usually no. Purchased points are non-refundable, and Bonvoy award pricing moves. Buy against a concrete stay when the math is clear.
Do purchased points help elite status?
No. Purchase bonuses are for award balances. They do not replace the night and spend rules that build Marriott Bonvoy elite status.
