I've been both buyer and seller! I can say the coach bags are authentic because they are screened. Jewelry however can be an issue if you buy plated make sure you r aware that plated jewelry will not hold up to everyday wear and tear. As a seller of jewelry I purchase jewelry made only in the USA and tend to sell only stainless steel because it will never change colors turn your finger green and is hypoallergenic! Don't let this one bad site ruin your experience! I also sell coach and they are authentic! And am always happy to show proof of sale! MY ADVICE IS TO TRY THIS BRAND NEW AUCTION SITE THATS IN ITS BABY PHASE, THEY TREAT BOTH BUYERS AND SELLERS WITH RESPECT AND DO NOT CHARGE THE SELLERS OBNOXIOUS FEES WHICH IN TURN CAUSES SELLERS TO PURCHASE CHEAPER QUALITY JEWELRY TO MAKE A PROFIT! I do not work for this new site but would like to see both sellers and buyers work together to meet the supply and demand of quality items. :) www.https//raiseyourpaddlez.com
