I bought a set of Time ATAC pedals from them back in August and have been using them pretty much as my main pedals ever since. For some reason one of the pedals became very stiff and was difficult to rotate on its spindle. So, I sent an email Performancebike asking about where to send them for warranty service. The pedals have a year warranty and I have long since tossed out the box and papers including my order invoice from Performancebike.
Less than three hours later I got a detailed email response, in short: Don't bother with warranty service, send them back to us for a refund or replacement, your choice. Don't worry about not having the invoice or paperwork, we will have a record of the transaction. DOn't worry about not having the original box, just pack them carefully and mail them back.
I think there is a certain NYC bike shop that could learn something about customer service by following this example. THAT is the way to treat a customer. Everyone here knows about Peformancebike already, so I doubt that I am increasing their customer base, but I like to spread the word when I am treated well.
