Last Monday 5/15 I ordered a set of General Altimax RT43's for my AWD E60. There were no rebates shown on TR's website at that time.
On Friday 5/19 I received an envelope in the mail from TR, with "IMPORTANT INFORMATION" in red letters on the front. Inside was a copy of my invoice with big red "PAID" on it, along with a copy of a rebate form for $50 off a set of four General Altimax RT43's. The eligible purchase period began the day I placed my order.
They didn't have to do that. I was already a "customer for life", having ordered many sets of tires over the last 20+ years.
But it's a great example of how a company can look out for their customers. Thanks, Tire Rack!
