Best Buy: Worst Decision.
The Reward Zone points brought the effective price of the camera down by about ten percent. I addition, BB offered 18 months, no interest. (I paid it off in two months).
1. Ill-informed sales experts
2. BB wouldn't/ couldn't issue Reward Zone Points certificates for redemption until three months after the purchase. Its corporate office explained the situation this way: duhhhhh. In order to receive my Reward Zone credits (worth $120.00) I had to return to the store, whereupon the manager canceled the sale, then issued me a gift card for $120.00. Fair enough. This was three months after I made the purchase.
THEN I sent the camera to the manufacturer for warranty work. I sent my receipt with the camera. The manufacturer couldn't verify that the sales receipt was authentic because the Best Buy manager had canceled the sale, and the manufacturer apparently called Best Buy to verify the sale. Upshot: my camera sat in the repair shop for 2 1/2 months before the sale was verified , the camera fixed and returned to me.
To give you an idea of the mentality of Best buy, check out this little news story about a guy who was arrested at Best Buy after he tried to make a purchase with two-dollar bills.
Here are two links which report the same story. The story was also carried on one of the news services back in April 2005.
