Priceless

I was at the mall today and walked into Gap just to look around. Lately they've been kind of overpriced and have some weird styles (i.e. the weird short polo shirts from like 1998, and jeans for $80) so I wasn't really expecting to find anything.
The sales associate handed me a little scratch-off promo code and it was worth $25 off a pair of jeans. $80-$25=still too much for Gap jeans.
So I found a really cute cropped pair that was on sale for 24.99, figuring they'd tell me I couldn't use the card on sale items.

Here's the register scenario:
Me: "This card is for $25 off and these are only $24.99, can I use it for this pair?"
Gap guy: "I don't think you can use this on sale items, and I really don't think it would make them cost nothing."
Me: "That's fine I'll just keep the card and come back and look another day"
Gap guy: "Well, let me just try it first really quick" (scans both)
Register: "$0.00"
Gap guy: "Whoa, that's pretty cool."
Me: "Free pants?!"
Gap guy: "It's your lucky day, and that was so cool I'm gonna give you another discount card"

The second card I got was worth $20 off another pair of jeans. I'm paying the good karma forward and giving it to my sister, lest I ruin my streak of luck with selfishness.

A pair of $80 jeans for free makes for a pretty good trip to the mall.
