That is why I prefer to purchase at Best Buy. Full refunds, few questions asked. More salespeople and they are more helpful too. Also better prices. But CompUSA has a greater selection.
It must vary depending on what city you're in. Here, Best Buy is on my list of places to NEVER enter. Sales staff is NOT knowledgeable unless you're there to buy computer games. I tried to buy a PC and monitor and told the guy writing up the deal that I wanted the box, the monitor and that he could save his breath because I did NOT want a "service plan," "extended warranty," or whatever it was that they called it. I told them that if they started pitching me, I would take my business elsewhere.
The guy couldn't resist. He started in and I said, "Pardon me, but if you say one damn word about a service policy or extended warranty, I'm walking and you have NO DEAL." He waved to someone, and she came over and SHE launched into the pitch.
I walked. I understand that at Best Buy, failure to pitch the warranty is grounds for dismissal - so these guys were damned if they did, damned if they didn't. But I REFUSE to listen to a pitch for any add-on. Even when I go to Sonic, I place my order and then add, "And that is ALL I want tonight." That works at Sonic, but at Burger King, I have to add, "No drinks. I have plenty of Coke at home."
At least they don't try this stunt at the grocery. It's damned tough to sell an add-on at the supermarket checkout.
OTOH, CompUSA has been pretty good here, and their prices on the "box" I was GOING to get at Best Buy turned out to be 100 clams cheaper.
