A promotion paid the same reward for a $25 purchase and a $0.25 one, so Phillips just found the $0.25 option and bought thousands of it

the problem

A reward or incentive program is priced per unit, per action, or per proof-of-purchase rather than per dollar actually spent, so the program's designers have implicitly modeled the reward's cost against an average customer's typical purchase — leaving the cheapest way to qualify completely unpriced and open to anyone willing to find it

background

what everyone would do

Read the promotion as most customers would, mailing in UPC codes from whatever Healthy Choice products you'd normally buy -- the natural way anyone participates in a per-code reward program, which never surfaces the gap between the cheapest qualifying item and the average one the promotion was actually priced around.

what they saw

Phillips saw that the promotion rewarded a UPC code, not a dollar spent, and that Healthy Choice's cheapest qualifying product carried a code worth exactly as many miles as its most expensive one. The company had implicitly priced the reward against a typical shopping basket's average item cost, leaving the cheapest legitimate way to qualify completely unpriced -- a gap that existed the moment the promotion launched, regardless of whether anyone found it.

the move

Phillips bought 12,150 individual Healthy Choice pudding cups from ten Grocery Outlet stores in Sacramento for a total of $3,140, then recruited members of a local Salvation Army chapter to peel the UPC codes off each cup in exchange for donating all the pudding itself — solving the labor problem of processing over twelve thousand individual containers while generating a genuine charitable donation and, per Phillips's later account, an $815 tax deduction for the donated goods. He mailed in the UPC codes exactly as the promotion's own rules specified.

why it works

By identifying the single lowest-cost item that still counted as a full UPC code toward the reward, and finding a way to solve the resulting labor problem (peeling thousands of individual codes) through a charitable partnership that also generated a tax deduction, Phillips converted every dollar spent into far more reward value than the promotion's designers had modeled for. Because he followed the promotion's actual written rules exactly, the company had no legitimate basis to refuse payment once the codes were submitted -- the exploit lived entirely inside the terms as written, not in any violation of them.

the payoff

Healthy Choice honored the promotion's terms in full, crediting Phillips 1,253,000 frequent-flyer miles — the majority to his American Airlines AAdvantage account, which also granted him lifetime AAdvantage Gold elite status, with the remainder split across United, Delta and Northwest accounts. ConAgra did not run a comparable per-unit mileage promotion again, and industry observers at the time noted the episode caused the company only limited direct harm relative to the publicity it generated, since the actual cost of the miles was borne mostly by the airlines under existing partnership agreements rather than by ConAgra directly.

where it breaks

This approach only works when a reward program's terms create a genuine, exploitable gap between the cheapest way to technically qualify and the behavior the reward was priced around -- a program priced per dollar spent rather than per discrete unit or action closes this loophole entirely, since there's no cheap item to substitute for an expensive one. It's also a one-time exploit once discovered: after the pudding-cup promotion generated public attention, ConAgra and other companies serve as a cautionary example that gets designed around, meaning any given loophole tends to close as soon as it becomes visible enough for program designers to notice and price it correctly next time.

what came after

The pudding promotion remains a widely cited cautionary example in loyalty-program and incentive-design literature for the specific failure of pricing a reward against a UPC code or discrete action rather than against dollars actually spent, and Phillips went on to exploit several other similarly structured promotions afterward, eventually reaching even higher elite airline status through the same basic method of finding the cheapest legitimate way to qualify.
