All Luxury Brands, denimoverstock.com, Appareloverstock.com

Has anybody dealt with All Luxury Brands, denimoverstock.com, Appareloverstock.com, bestbargainsever.com or highendtrading? Do they only sell 100% authentic? Will they supply paper work if needed. I'm looking for a trustworthy supplier for designer name brand apparel that will strand behind their products, if in case ebay would pull the listing in beleif that it is fake. I just had this happen with my Ralph Lauren Polos and now I'm fighting with the supplier for paper work to send to ebay. This supplier claims to sell only 100% authentic department store overstock, closeouts, and shelf pulls.
I don't need the headache of worrying that my products that I'm selling could be counterfeit. I can't verify apparel myself and I can't have every item I sell verified by a professional before listing it. Any info that can be given to me about any of the above suppliers or any recomendations of other legit trustworthy suppliers would greatly be appreciated.
Thank You!

www.denimoverstock.com Has been reviewed by members and so far all positive reviews. And is located in our directory.

www.bestbargainsaver.com from what I tell they buy from liquidity services and resell the lots. I havent found any bad info on them as of yet.

www.highendtrading.com I cant find any info on this website. Which in my eyes is a bad sign. Therefore I advise against using them.

www.allluxerybrands.com I cant dig much up on them and so far I cant find any reports on thier products being fake. I think they are buying from liquidity services as well and selling off the lots in individual orders.
