How a convenience chain learned which rebate wasn’t worth chasing.
A beverage supplier offered a growth rebate on a new energy drink, tied to a 2-for-$5 promotion and four months of signage. On paper it paid. Cortex ran the whole deal, and it didn’t.
The difference
Same question. Different results.

Answer
The rebate pays 1¢ a can up to 400,000 cans and 2¢ above. With the supplier’s forecast of 450,000 cans, you’d earn about $5,000. Sign it.
Just an answer.

Answer
Don’t sign it as offered. After the discount and cannibalization, the deal loses $138,900. Offer a $2.99 single can in 38 highway stores instead. +$21,600.
A decision.
01 · The challenge
A rebate that looked like free money.
The supplier paid 1¢ a can on the first 400,000 cans and 2¢ a can above that, from January to June. To earn it, every store had to run 2-for-$5 on the new line and keep the signage up for four months.
Working it out by hand took an analyst about a week: last year’s sales, a guess at the lift, the discount, and whatever the promotion took from the energy drinks already in the cooler. Usually, the team just signed.
- Rebate on offer1¢ a can to 400,000, then 2¢ a can
- Supplier forecast“Easily 450,000 cans”
- Promotion costNot calculated
- InstinctSign it. Rebates are free money
02 · The finding
The rebate was real. The promotion that earned it wasn’t.
Cortex predicted volume with and without the promotion from two years of transactions, store by store. It priced the discount on every promo unit, then measured what the deal took from the energy drinks already on the shelf.
Almost two of every three extra cans came from shoppers who would have bought a different energy drink. Only 38 highway and travel-center stores showed volume that wouldn’t have happened anyway, and there a simple $2.99 single-can price did the job.
03 · The decision
Go back to the supplier with a smaller, smarter deal.
- Proposed a $2.99 single-can price in the 38 stores where the lift was real, instead of 2-for-$5 everywhere.
- Negotiated the first tier down to 300,000 cans to match the narrower rollout.
- Set Cortex to track the deal weekly and flag it if it falls off pace for the tier.
04 · The impact
What changed.
A rebate is only money if the promotion that earns it pays.
We used to sign anything with a rebate attached. Now we know which ones pay before the posters go up.
Signage stays up for months, so a bad deal keeps costing long after it’s signed. The time to know is before.
