I bought my Nike BF III on e8ay and it came with the 6 month outsole warranty card. On the warranty it said i need to staple the receipt on the card and then send it to nike. But the seller didn't send the shoes with a receipt. But i still have the paypal information and the e8ay information with the date i purchased it . Will this be sufficient information for me to be elegible for the 6 month warranty?
