When we finally got the register to pay, the sales gal said that we "kinda had to use all $100 at once". What? I've never heard of such a policy. She called her manager, and confirmed that these were indeed the rules. Well, I didn't want to buy $100 of stuff I wasn't 100% into, so we left without anything. I'm definitely going to use the certificate, but the whole thing seems a bit odd*.
On the bright side for American Apparel, however, they've expanded their jeans, shoes and bra selections. I was delighted to see that there are Made in USA bras now with underwire! Yes! I know some people hate underwire, but not me! I probably would have spent the $100 on bras, but I think they still have a bit of "engineering" to do before they've perfected the boob fit, but they'll get there. Practice makes perfect! It was a good day with Brian, though!
*UPDATE (01.07.13): Today Brian called American Apparel to ask if the clerk was correct about the gift card policy. Apparently, she was wrong, and if you get a gift certificate, you can use it in increments. Maybe she was confused.
