My father buys and sells collectible currency and his site that was created back in the early 2000's wasn't cutting it for today's mobile web. He wanted to sell inventory online aside from eBay. This site has run strong for the last couple years, it's see quite a few transactions, it's very easy to find what you're looking for and buy it with the click of a button while also being very secure.
This site is built on the OpenCart content management system, a system built for selling online. This site utilizes SSL protection and processes all payments securely through paypal. The CMS provides an easy to use secure login system and a easy to use admin area for processing orders.
