So much of what they sell is obsolete. Up until about five years ago, it was worth the drive because if I needed something they sell, I'd also browse their CDs and DVDs. Then they cut down selection as less people buy those things.

You were actually able to talk to a salesperson on the floor? Last time I was there you practically had to chase down and tackle a saleperson to get any service. I'm like you, I used to go there all the time but in the last several years I've only gone twice and that was because my portable MP3 player broke down and I wanted a replacement right now to listen to during that day's work out.
In my experience, everything carried by Best Buy is found in the manufacturer's current assortment, and usually represents every tier the brand offers. Have you ever investigated the model variety and model years on display at your local Wal-Mart? Do they even carry 4K HDTVs?
