The truth behind the aggresively pushed extended warranties at Best Buy can be found at WarrantyBullshit.com.
From what I’ve read online, all Best Buys are the same – their floor managers turn their sales employees into braindead assholes who will try to force you into shelling out even more money for a totally worthless extended warranty, often on items as low as $50. Sometimes they’ll even refuse a sale altogether if a customer doesn’t go for the extended warranty.
The retail experience sucks ass when quotas and commissions are involved – just look at Circuit City! Pushy pushy!
