Not that I can think of. There are stores that I don't particularly like, but if they have what I want for the price I want, I don't give a damn about principles. Most customers these days are just as unprincipled as the stores anyway.
There are stores that I'd rather not have to go to, like Walmart, but in a pinch I'll go there. Just bought Guitar Hero World Tour there for $99 a week or two ago.
Even after bad service, I don't really hold a grudge if they can save me money in the long run. Home Depot pissed me off when they sold me a partially used can of stain, then wouldn't take it back. I've probably spent $10k there in the last year, and they've saved me a lot of money. I can live with getting burned on a can of stain in exchange for the money I saved.
