how many times can i exchange a tv at best buy?

[Donna C]

so i purchased a tv from best buy, my fiance works there so we got to use her discount...the first tv we got had a stuck pixel..the exchange we got for that tv had 7 stuck pixels..i took that one back and now we are waiting on them to get another shipment of those tv's in because they are out. i was just wondering if there is a certain number of times i can exchange a tv..we paid $1k for it so i want it to be perfect..but i dont want to piss off the people there but the manager said he understood, he said if he spent that much on it he'd want it without any problems..i dont know if he was just being nice though
