A slow-moving bat found 167 buyers in six days.

A baseball equipment brand had deep stock of one bat, and a new edition on the way that would make it even harder to move. It ran a drop: group pricing, referrals and a countdown, pushed by its own creators. The drop brought in $32,062.33 from 167 bats.

01 — The challenge

Deep stock, and a new edition on the way.

The brand had a lot of slow-moving inventory on one bat. Once the next edition launched, shoppers would have even less reason to pick this one.

Inventory

Slow-moving stock

A large quantity of one SKU sitting in the warehouse.

Timing

A new edition coming soon

The next release would make the current bat even harder to sell.

Resources

No new content

The test had to run on assets the brand already had.

In short: the brand needed a reason to buy now, before the next edition arrived.
02 — The solution

A drop: the more people join, the lower the price.

Think Groupon meets TikTok Shop meets gamification. Shoppers join a group for the bat, the price unlocks in tiers as the group grows, and every buyer gets a link to bring friends in before the countdown ends.

Group price tiers

At 100 buyers, the price dropped from $319.99 to $191.99 for everyone.

A referral link per buyer

Buyers who brought friends could unlock a better tier on their own.

SMS and email

Progress updates and the final price went out by text and email: 471 SMS, 554 emails.

Existing assets, creator seeding

The drop page reused the brand's video. A few of its creators shared it to start the group.

The group buying process: users join, invite friends, unlock better pricing and buy.

04 — The referral layer

41% of buyers were invited by another buyer.

Every buyer got a personal link. Inviting friends lowered the price for the whole group, and buyers who invited enough of them unlocked a better tier for themselves.

05 — Momentum

Creators started it. Buyers kept it going.

Most of the group joined on day two, right after creator seeding. From there, a steady share came in through other buyers' links.

Mid-drop
We added a tier to push it further.

The campaign moved fast enough that a 200-buyer tier at 50% off was added while it ran, giving the group and the top referrers something new to reach for.

06 — The takeaway

Turn a clearance SKU into a group event.

With existing assets and a handful of creators, a drop gave shoppers a reason to buy now and to bring friends. Referrals brought in 41% of buyers. It sold 167 bats for $32,062.33 in six days, ahead of the new edition.
