I received an e-mail confirming that my rebate was approved on October 11.
The rebate did require an "Invoice", but Outpost never supplied any document with the word "Invoice" on it. Covering all bases I send in:
A screen print of the order confirmation page.
A copy of the packing slip.
A copy of the "Proof of Purchase" E-Mail Outpost supplied when I
contacted customer service and asked for an Invoice.
