Thanks unity1 for the discussion. Although you order through TGG ebay store, the Receipt/Tax Invoice is identical to the one you would be issued if you purchased the in store. I have notched that there is no mention of eBay on the Receipt/Tax Invoice, so you would have no problems to claim this cash back offer.
