Registry question

Okay. . .this might sound like a weird question, but here goes:

FH and I decided that we can't wait to have the Dustbuster on our registry in our hands since our vacuum is so cumbersome. We want to go out and buy it at BBB today (where we're registered for it). Can we get a discount since it's a registry item, even though we're buying it?

You can use a 20% coupon on it.....they don't give an additional discount because you are registered with them!!!
