I had the most recent set of tires I bought online mounted at Walmart.
The guy doing the work took his time, gave me the option of using tape weights or flange weights, mounted my asymetrical tires with the correct orientation and did not mess up the TPMS although I had rebuild kits installed. He used a torque wrench as well.
When having either asymetrical or directional tires mounted I always mention this to the installer just to avoid any misunderstanding.
The price was competitive with the local mom & pop I usually use and includes lifetime balance and rotation.
I tried Wally this time because I needed the tires on right now, since the car (our Forester) had experienced a blowout on one of the factory Yokohamas at 56K.
I had really liked the Yokos up until then.
Fortunately, I had a set of Pure Contacts ready to go in the garage.
Walmart will also order any tire that might strike your fancy.
Based upon my experience with this TLE, I'd go there again, although I'll also throw some work at the local shop.
The TLE was busy with oil changes, and the price they had for a change with QSGB was so low it almost wouldn't pay you to do it yourself, although most of us would anyway.
