I recently bought a mac pro from Amazon which had a $150 rebate via rebateshq.com. The instructions said: Once you receive shipment of your order, you may redeem this rebate by reading the rules below and logging on to the following site: www.rebateshq.com/amazon-rebates Please allow 8-10 weeks for processing $150 Rebate Promo ID: 08-105642 Valid Purchase Dates: 02/19/2008 to 03/11/2008 Last Submission Date: 04/11/2008 so when it arrived I went to the site and attempted to submit my rebate. Not a chance! Your rebate is unavailable for submission at this time due to one or more of the following reasons: - Your order may not have been processed for shipping. - You may have entered an incorrect Amazon.com Order Number - The e-mail address entered does not match the address for the Amazon.com Order Number Please re-enter the information or return in 24 to 48 hours to submit your rebate So I attempt to contact them...nada...so I threw an email to Amazon customer support who came back the next day with: Greetings from Amazon.com. I am sorry to hear that you are having difficulty in redeeming the rebate of $150.00 for which your order is eligible. However, please understand that due to some technical errors you are unable to submit the rebate form. Therefore, to correct this error, I have requested a refund of $150.00 towards the rebate amount to the payment method you used for your original purchase. This refund should go through within 2 to 3 business days. You should see it as a credit on your next statement. FYI the rebate posted the same day, way to go Amazon!
