I'm looking to buy a receiver and I found a Denon AVR-1712 on ebay for $325. It says it is brand new, and I contacted the seller and he confirmed that it is indeed new, and I can return it within 7 days if I'm not happy. I also asked him if he will ship it with a receipt, and he said he doesn't ship receipts.
So my question is, do you need a receipt for Denon warranty purposes? Or just the physical warranty that should come in the box?
I'm new to HT so any help is appreciated.
