They are known for this BS. Last Black Friday I bought a MacBook Pro in the state I was in for the holiday. Decided I wanted the MacBook Air. Returned the pro for the 11" air. After I got that home I decided I wanted the 13". They exchanged no issue. Few weeks later I bought a galaxy tab 7". Realized it was a piece of junk. Went to return it and was told they would not take it back. Receipt was spit out that told me to call a number. I called and was told I returned too many things in a short period. I had to keep that galaxy. I got on Facebook and blasted their page. I got a message to give someone a call. They took it back. I wrote them off and only go in there to see what I want from another store. You should be made aware of this before you are stuck with a product.
Well then maybe you should stop the excessive returns and exchanges? Best buy or any retailer for that matter isn't there for you to simply loan out their merchandise. These items lose some of their value when you return them, especially after you have already opened them.
I for one am glad to see a lot of these retailers step up with harsher return policies, for far too long people have abused them.
