I bought a Samsung Sound Bar from BestBuy (Whitehall PA) on Dec. 4, 2017. It had to be sent back 3 times for repair. In order to get a refund from Samsung, they are requesting a copy of the receipt from BestBuy. Can Best Buy provide me with a copy.

Yes. Just ask customer care or anyone in the home theater department to look up your customer profile to re-print receipt.

Yes they should be able to if you paid with a credit card or using a best buy customer number. I usually have the receipts emailed to me for safe keeping, I suggest that for everyone.

As long as you used credit card or used a rewards account then yes.
