I'd grab a couple of the $5/$25 coupons, and ask the staff to help you arrange the transactions. If they are offering the $10 gift card for $5 deal, then in Trans. #1 you buy $25 of stuff, plus a $10 gc for $5, less the $5 coupon = $25. In Trans #2 you buy $25 of stuff, less the $5 coupon, and use the $10 gift card toward payment = $10. Total = $35 for $50 value.
This seems like a crazy amt of $ for a stuffed animal but unless you are able to steer your DD toward the least expensive bears (they usually have a couple that are only $10 or so) and the least expensive clothes, and talk her out of the smell/sound, be prepared to maximize discounts!
As I recall you can also use your AP for 10% off, but I'm not 100% sure I was able to use coupons along with the discount; you could always call ahead to ask.
ETA: Whenever we have been there, there were very different items on the second floor than on the first. Probably some of the same bears/animals, but upstairs they have the less expensive/outdated bears, and there were definitely different outfits/accessories. As DD loves to spend hours at that store, trust me, I tried to talk her out of upstairs telling her it was the same, but a staff member corrected me and indeed I was wrong.
