Many stores ask for it. Radioshack I believe is a prime example of this. I've never heard of them hassling you if you refuse however.

RadioShack only asks for your zip code. It pops up and asks when ringing something up. They can just hit escape if you don't want to tell them.

Radioshack stopped doing that a while back.

Ah, good to hear.

Thats when you give them the address: "123 Biteme Street" (pronounced Biteeem)... Or just tell them no

I meant an online store. I was too angry when I was typing my comment.
