Can anyone help...I have been a coin and paper money collector now for years now...i ran into these sellers that sell on eBay http://myworld.ebay.com/skylinecurrency and i was kind of scared to purchase on eBay any currency so i started with s $5 bill they had that i needed just to see the quality, shipping, if it was real or not...when i received the bill it was as described and it was awesome for the price...currently i was able to find some rare notes from them and now they just opened there own website http://www.skylinecurrency.yolasite.com/ and im wondering can this be a scam or how can i be sure i will be safe to purchase from them on the website...(the website is cheaper then prices they have on eBay) please help...thank you
