Tire chains, outside of DT, have a few tiers of tires:
Junk you would never want
Crap that you would use, but are priced too high
Name-brands, but only the worst models, and ++ pricing
Premium tire models at Ferrari prices
So, better chances of a square deal at a retailer like Firestone, or a place you can order your choice of tires at a decent price, like WalMart
Mail-order BYO to car dealership is great if you have a good relationship with them.
Mail-order BYO to a place like W*M is ok, but they charge about $100 M&B now.
I'm on really good terms w/local Firestone, my BYO tires are $52 a set M&B now! They love me there.
