Hi, I have a couple of spare Windows 7 license keys which I have no need for. I have a few of each edition and if anyone is not willing to pay full amount for the purchase I can sell RETAIL keys to you. Let me emphasize this, these keys are RETAIL keys not for RC use. I own these keys and they are not from Technet or any other source. I am willing to negotiate the price depending on each edition. If you are interested please PM me. Payments method is Paypal. If you feel uneasy about this transaction I am willing to open up a trade via eBay. Thanks!
