For many years, jamba juice was running a promotion: buy a $25 gift card, get a free jamba juice. So one day I bought a gift card, got my free razmatazz, and was about to head out on my way when I doubled back.

Me: "I'd like another $25 gift card please."

Cashier: "That will be $25. What is your free smoothie?"

Me: "Peach pleasure."

And then I would pay with the previously purchased gift card, creating an infinite loop with a sunk cost of $25. I was only once refused. I netted at least 50 jamba juices for me and friends..I hope to incorporate this into a screenplay some day.



I did this with Blockbuster a few years back. I believe it was a free $5 gift card for each $50 gift card you purchased. Most stores I've seen now have a policy of not letting you buy gift cards with gift cards.


That should teach them about recursion :)

Brilliant to spot the loophole on the spot.


They did not arrest the recursion by specifying that the free jamba juice offer did not apply to gift card purchases?


while cute, i'll call crap on this :) they specifically make you buy the gift card with a credit card, not another gift card.


You win.
