Absolutely not affiliated in any way. If I was, there would be a disclaimer. Yes, there are other vendors; however, do you know for a fact that they have tested the RAM they sell with Macs? Are they as Mac friendly as the two most recommended here? Do they offer excellent customer service and lifetime warranties?
And, if you are not affiliated with the two no one here has ever heard of, why was there a disclaimer at the end of your post that you may receive compensation for your recommendations from those sites? Those are typically necessary only if you are affiliated. Per the ToU, we are only to recommend sites if someone asks and advertising is not allowed.
