I had TONS of problems with Performance AND nashbar, both owned by the same company. They were charging me more or less than the receipt. It was usually only a few cents difference, but one time it was $6 and I noticed. I went back through receipts and saw 24 errors of 35 orders. When they ignored my emails, I filed a BBB complaint which took over a year to resolve. If I buy from them, I do so by check now so they cannot upcharge me. I don't trust them at all. Customer service has been very lousy since they were both bought out two summers ago. Buyer beware. It's a dang shame they, Nashbar, makes the standup best bib short ever made, the ultra.
