I found someone who offered a great deal on 64g IPP 10.5. Saying it's 1 week old but he lost the receipt and need cash. Sounds weird to me because I am sure you can go back to the store and they will pull your receipt based on the barcode/serial#. He provided me with the serial and I ran it through the Apple website. My question however is if there is a way to know if it's refurbished? or anything else? He offers for $495 (which is really 450+ tax) so good deal. Thoughts?
