I belive this is the complete list of the non-concession stores in the U.S., the ones that share their computer databases, and can cross-reference your purchases.
and I think Waikiki.... That's all!
If "yours" is not on the list...it is independently owned.
Some SA's will of course never bother to look, but these stores have connected databases, so if you are in Chicago, (for example) the can (if they are not lazy), check for a scarf, or belt, or bracelet you may be looking for (probably will not do a bag unless you are very VIP, ) and have it transfered to your local store. But it is only amongst the stores listed above as far as I know.
Waikiki - yes!
I called them, and they had my info on a screen within a minute.
So I wondered if they put in whatever I purchased from them.
Are purchases entered into the database along with address and phone
