If you like buying your smartphones at Costco, have I got news for you. Sounds like the king of giant ketchup dispensers will be offering the Atrix 4G as part of its relationship with AT&T, and for the same $150 on-contract figure Amazon quoted (and then quickly unquoted) yesterday.
Lifetime supply of toilet paper not included
I know I'll be getting an Atrix 4G come launch day, but I think I'll take a pass on Costco as a vendor. Unless the phone comes with a free slice of Costco pizza and a polish - then I may have to reconsider.
