Nashbar & Performance "sale" emails usually arrive within an hour of each other, considering they're the same company.
If somebody else (i.e. Cambria) has a different sale, Nashbar/Performance usually matches the offer within 24 hours via email.
I'm also noticing that Nashbar/Performance's "sale" prices are no different than what they were selling items for 2 months ago. They just jack up the MSRP to make it look like a deal.
Their SS conversion kits have gone up in price the last 6 months. Ditto for their house brand road wheels.
