Purchased a set of Calloway X-22 irons. Represented on the web site and by email when I questioned shopofgolf to be OEM. Long story short, the clubs are not OEM. I have confirmed this with Golfsmith, a national retailer, and they are sending one of the clubs directly to Calloway for further confirmation. Shopofgolf.com originally offered me an 8% refund. When I refused, they said my definition of OEM must be different than theirs but bumped the refund offer up to 15%. Mastercard has agreed to refund all of my money as soon as I obtain the letter from Callaway.
Follow-up 2-24-10: Got the club and letter back from Callaway today. The clubs I bought are counterfeit.
