I was at a bridal show on Sunday. I filled out a registry card for BB&B for more information - I gave the girl half and I kept the other half. As I am reading the "fine print" it says on there that STORE CREDIT WILL BE GIVEN IN THE EVENT OF A RETURN WITHOUT RECEIPT OR PACKING SLIP".
Yep, they no longer give cash for items purchased for your registry that you want to return. Here is it on their website too...
