Has anyone ever seen fake/counterfeit MAC shade sticks?

There are two shade sticks right now on ebay that I know for a fact have been discontinued for quite some time now. The seller however, is only listing them as being "sold out". There are pictures of the actual shades sticks, not stock photos. In fact, I checked their other listings and there are no stock photos at all. This person is listing predominately MAC auctions and i've checked the seller feedback and it's all good for the MAC products, however the bidding has ended at very low amounts for all, which may or may not just be a coincidence. I wouldn't buy anything else from this person out of caution, because if I do buy any MAC on ebay at all, I buy it from a few reputable sellers that I know and have been selling MAC on ebay for years. I have never seen or heard of fake MAC shade sticks, so has anyone else seen or heard of this product being counterfeited? As many MAC products online are not the real thing, I have never seen these faked.
