This place is messy but other than that I've been lucky getting awesome deals from them. For example, I got a $4k TV from them 2 years ago for $200 less ($600) than the next best offer anywhere else ($800) so definitely substantial savings. When I got home, I realized that the TV had a wrong remote so I went back to the location and the manager apologized and got me the correct remote.
Keep in mind that you're usually getting a deal there - it'd be foolish to expect the same level of service with more expensive places. Be patient, positive and enjoy the savings.
