I got precisely this vibe, too. Didn't quite pick up on it the first time I bought some gear there. Price seemed about $25-30 more than I expected, but I didn't notice until I got to the car, and noticed no details on the receipt. It was like from an old adding machine print out, FFS.
Second time I went, I had forgotten about my first experience, as it was a couple years later. And I wanted to like the guy, I was in HS when he was the SU kicker.
And then when he pulled the switcheroo on sale items that second time I came in, it brought back memories of the first time when he ripped me off with his made up prices and non-receipt,
So, I decided that was going to be the last time. But you don't cause a scene in front of your family, so I put back the sale stuff he said wasn't actually on sale. I wound up still overpaying on the 2 or 3 things I really wanted to get.
Shtt bag of a guy. He should sell aluminum siding. I hope they condemn his damn building. It's an eyesore. I've had commercial tenants in some of his buildings where we had to sue him (I think he owns 2 or 3 on that corner of Marshall), just to take care of the place, and not go into their stores when they weren't around. Just a basically dishonest guy, all around.
