Amazon has confirmed that Prime Big Deal Days returns on 6 and 7 October 2026, and Target has put its own Circle Deal Days on exactly the same two dates. If you sell on Amazon, your autumn advertising plan just got a deadline.
Retail Dive reported the clash on 15 September 2026, and Amazon has published its own Prime Big Deal Days FAQ confirming the dates. Two days, head to head with a rival sale, right at the start of the Christmas run-in. That is a lot of demand arriving at once, and a lot of competitors bidding for it.
Key takeaways
- Prime Big Deal Days runs 6-7 October 2026, and Target Circle Deal Days runs the same two days.
- Fix the product page before you raise the budget. Ads cannot rescue a weak listing.
- Keep branded and non-branded campaigns apart so the numbers mean something.
- Budget for a two-day spike, not a normal week, and check spend at midday.
- Plan the week after the sale, not just the two days.

What changed this week
Amazon has confirmed Prime Big Deal Days for 6 and 7 October, with new deals dropping through both days and Prime members getting exclusive access. Target announced Circle Deal Days on the same two dates, with its paid Circle 360 members allowed in a day early on 5 October.
For an advertiser, the discounting is not the news. The calendar is. You now know the exact two days when Amazon search traffic will spike, and that a large competing retailer will be spending hard to pull the same shoppers elsewhere. Three weeks is enough time to prepare properly, and not enough to leave it until the Friday before.
Fix the listing first
An ad sends someone to a product page. If that page does not convert, extra traffic just costs you more money at a worse rate, so spend this first week on the listing rather than the campaigns.
Check stock cover first. Nothing burns budget faster than paying for clicks on something that sells out on the morning of day one, and a product that runs out mid-sale loses its ranking as well as the sale. Then look at the page itself. Is the main image clear at thumbnail size? Does the title say what the thing actually is? Do the bullet points answer the questions people keep asking in the reviews? If you are running a deal, check the price history too.
Split branded and non-branded
If your own brand terms sit in the same campaign as generic terms, the report you get back is an average that flatters. Branded searches convert well and cost little, because those people were coming to you anyway. Generic searches are where you actually buy new customers, and they cost more. Averaged together, a poor generic campaign hides behind a good branded one.
Separate them now, while there is still time to read a fortnight of clean data before the sale. It also forces a decision you need to make anyway. During a big sale, competitors will bid on your brand name, so are you defending it or not? Defending is usually cheap. Finding out on 6 October that someone else sits above you on your own name is not.
Budget for two days, not thirty
Daily budgets sized for an ordinary Tuesday will be gone by mid-morning on 6 October, and your ads will stop at the point when the traffic is at its best. Work out what you are willing to spend across the two days, raise the daily budgets the day before, and check spend at lunchtime on each day rather than at close of play.
Bids need the same treatment, because costs rise during a sale when everyone is bidding. Raise the bids on terms that have earned it and leave the long tail alone. One warning: do not restructure campaigns during the sale. If something looks wrong on day one, change one thing rather than five, or you will never know what made the difference.
The week after matters
Plenty of people browse during a sale and buy a week later, especially on higher-priced items. If you switch everything off on 8 October, you hand those sales to whoever kept advertising. Keep retargeting and Sponsored Display running through the following week at a lower budget, and let the attribution window close before you judge anything.
When you review it, compare like with like. Two sale days against two ordinary days will always look wonderful and tell you nothing. Compare the whole of October against last October, write down what you changed and when, and agree one decision for November while it is fresh.
