Carlisle rant!
That sucks and I wouldn't buy stuff from them either, even if they were the low price outlet. I'd walk to one of the more courteous vendors with the same item and ask what they could do to get close. Don't care if it's 120 out, crappy seller/vendor attitudes aren't cool.
Even to the most obvious of jackassery buyer at swaps, I'm always polite... PERIOD! It's been in the very high 90's-low 100's at some swaps out here. Get more bees with honey! :) The obvious parts flipping crew around these parts know they get a different price than the end user.
