Don't Buy Best Buy

Making a purchase soon? TV or anything else electronic?  Before you buy Best Buy look close at their return policy.  15 days and that's it.  They won't even listen to you.  I was buying a tv I wanted before the Super Bowl and I was in Best Buy before Christmas.  I was told not to worry about the 15 day policy that they would extend it til the end of January.  This is the time to buy.  Found it on January 20th at their store $100 cheaper.  They would not look at my receipt and told me the kid who sold me the tv flat out lied and they don't care about my business.  I took this as a $100 lesson and went to Costco to look at tv,s for the bedroom.  They told me their return policy is 90 days for any reason.  I'm still shopping but I'm done with Best Buy.
