This is probably the stupidest question in the world. But Google is no help and neither is the BB&B FAQ site. Someone purchased a gift off our registry and we received it in the mail...but I have absolutely no idea who sent it. No packing slip or card or anything, just the gift in its store packing. Please tell me I'm being dumb and there's an easy way to see this. I need to know who gets the thank you card...
