Discount Tire just lost my business

Went to Wal Mart to get a spare when I did the scarebird brakes (old spare was 13" and wouldn't work with discs). told them I wanted a cheap 14" for a spare, they asked what size, I said anything around a 205/70, "have to have a size" I walked over to the display looked at the sizes in their cheapest tires and picked a size then told them that size.
My Dakota was overdue for an oil change and I was pressed for time, so I took it to Wal Mart. they tell me the left turn signal doesn't work(always did before)looked at the paper and it says a wiring problem with left turn signal. The ignition switch was always finicky, I had to have the key in just right or it wouldn't turn(felt like using the wrong key), after they changed oil ,it turns, but is now very stiff and won't turn to accessory, and one speaker sounds like it blown(that could be coincidence, I suppose). After that I will never go to Wal Mart automotive again.
