Prime Big Deal Days Case Study: Nearly Double the Sales on $3K a Day

Prime Big Deal Days, October 6 to 7, 2026, vs. the same event in 2025

Plenty of small ad budgets run dry by lunch on a Prime event day. This pet treat brand made its $3K a day last into the evening, and nearly doubled its sales. Over Amazon’s Prime Big Deal Days, October 6 and 7, 2026, sales rose 92% on day one and 89% on day two against the same days a year earlier.

Small budget, big day, one problem

The partner sells treats and supplements for cats on Amazon, from lickable treats to kidney support. Cat owners buy them again and again, so a shopper won during an event is worth more than one order. Every new customer is a reorder waiting to happen.

The catch was the budget: $3K a day in search ads, on two of the most expensive days of the fall. Spent freely, a budget that size can be gone by early afternoon, and then the brand vanishes from search while shoppers are still buying. The partner’s goal was clear going in: 2.5 to 3 times a normal day, and a clear win over the same event in 2025.

The play: make every dollar last

  1. Put the budget on a timer. The daily budget was released in stages across the day instead of all at once, so the ads were still running into the evening.
  2. Go after shoppers who haven’t picked a brand. Bids went up on non-branded searches, where people look for a type of treat, not a name.
  3. Sell the second product. Remarketing and cross-sell campaigns reached shoppers who had viewed or bought one product and showed them the next one, and video ads showed the products in action.
  4. Bring in traffic the budget didn’t pay for. The partner ran its own Meta ads pointing shoppers to the Amazon listings, adding visits without a single extra search click.

The scoreboard

By the middle of day one, sales had already passed $29K on $3.6K of ad spend, a 12% TACoS. Day one closed 92% ahead of the same day a year earlier, at five times the brand’s average day over the month before. Day two closed 89% ahead of its 2025 match.

Why the clock beat the checkbook

On an event day, every brand raises its bids, so a fixed budget burns faster than normal. When it runs out, the brand disappears from search for the rest of the day, often while people who shop for their pets after work are still browsing. Spend the whole budget by noon, and you have paid for the morning and handed the evening to someone else.

Spreading the budget across the day kept this brand on the page the whole time. The jump in conversion suggests the clicks it did buy came from shoppers ready to order.

A small budget can win an event day. It just has to still be awake when the shoppers are.

All figures rounded, each in the less flattering direction. Weekly figures cover the full week containing the event.

The weekly comparison includes the two event days, so it measures the event’s effect on the week as a whole. Year-over-year results are reported as percentages and an index to protect the partner’s data. The partner’s own Meta ads also drove traffic, so not all of the gain comes from Amazon advertising. The partner is anonymous. We will update this page after the 2027 event.

Steal this for your next event

Three checks to run before the next one.

First, find out when your campaigns ran out of budget last time. If it was before dinner, you paid for the morning and missed the rest. Second, find your best hours in past sales data and release budget to match them. Third, look for shoppers you don’t have to buy on Amazon. Outside ads, email to past customers and remarketing all bring people to the page without fighting for event-day clicks.

Budget decides how many shoppers you can reach. Timing decides whether they are ready to buy.

Frequently asked questions

What is day-parting on Amazon?

It means setting different budgets or bids for different hours of the day. On an event day, it keeps a limited budget from running out early, so ads are still live during the hours when your customers buy most.

When do Amazon campaigns run out of budget during Prime events?

Often earlier than normal, because click prices rise and traffic is higher. A daily budget that lasts all day in a normal week can be gone by midday during an event. Check the time each campaign ran out in your last event report.

Do pet products do well during Prime Big Deal Days?

They can, because pet treats and supplements are bought regularly. Event shoppers often stock up on larger packs, and a new buyer during the event can become a repeat customer for months.

Should I send Meta ads to my Amazon listing during an event?

It can help, if the listing converts well and the deal is live. Outside traffic adds shoppers without bidding against other brands on Amazon. Track it with Amazon Attribution so you know what it added.

Does Canopy plan event-day budgets?

Yes. Canopy brand managers set event budgets with the partner, schedule spend through the day and adjust during the event.
