I like the Geek Squad over at Best Buy. When I finally got a laptop, the Geeks answered everyone of my stupid questions, respectfully, and w/o once rolling the eyes. At least while talking to me.
To answer both your posts
1. Walmart unlike Sam’s Club does not require membership, and has a robust online presence not just brick and mortar.
2. If you are happy with Best Buy that’s great, just keep in mind that the Geek Squad guys have a history of pillaging information and images from computers they work on.
