Me, too, Lily!
So weird that they pretty much forced that gift card on you, mailing it!
But I wonder why they couldn't have just ordered it in the store when you were standing there the first time! They could have lost a sale because it gave you the opportunity to look elsewhere online, since you were going to have to do a Web order anyway (and, if you were me, probably frustrated with not somehow being able to get what you wanted the first time out).
Anyway, happy new dishwasher!
