I share your caution with Nashbar. They were purchase awhile ago by performance. At first I loved a couple of their products and shopped the returns section often. Suddenly almost every purchase had a problem. First it was product not in stock after getting a confirmation. Then I had a billing problem with them AND with Performance. I discovered that they were fraudulently over billing my credit card. It was by $0.01 or $0.05 cents usually. I looked through ALL of my receipts and double checked with credit card statements and found over 25% were over billed. One was for over $6 on a $20 order.
I had to file a BBB report as customer service only replied by commenting "What was the reason you were overbilled?" I tried to explain that my receipt and credit card charges didn't match and this happened on two different cards(citi and chase). They just stopped responding, my performance points disappeared and the BBB is trying to get a response from them. I also filed a report with my credit card companies which immediately issued refunds to me and indicating they were investing the issue. I lastly notified the FTC as this is illegal actively and performance inc is a little arrogant about it. It would have been dropped if they had just refunded the overcharges to me.
It makes me sad because a couple of their products are exceptional, but I will not do business with them unless I can send a check or use pay pal as they cannot be trusted to bill appropriately to the credit card. Careful!!!
