700NF and it's rebate question..

[Imported]

Not sure if it belongs here, but since it wasn't a hot deal and it is video related I'd thought I'd ask away. I purchased the 700NF before the $30 rebate ended from Onvia and I don't know what to send to get the rebate. It asks for receipt and UPC; I have the UPC but would a print-out of the order from Onvia count as the receipt or would the packing slip count as it?
