I'm sorry to hear your store is one of the ones closing. They're such a special experience.
I don't have a coupon, but a different tip. Take a look a the sale items on the web page. If your daughter is interested in one of those, you can get the sale price but you'll have to price match it to the AG website. They won't have signs and it won't ring up automatically, but they will honor the price at the register if you show them their own website sale.
