It has a lot to do with what I put up for auction and how much research I do to make sure that the books or other items I am auctioning are sellable. Still, there is a lot of chance involved too, no matter how carefully you research and package your auctions. I am working on being more selective and doing more research before putting my items up for auction. I think that is becoming more important as the online sellers market becomes more competitive. I don't have an eBay Power Seller designation because my sales come from several different online venues.
Sales vary during different times of the year.
During the next few months I plan to double that figure by increasing my amount of items for sale online and promoting my business more than I have in the past. Since I primarily sell used books, the zShop is an excellent venue for my business. I don't have a retail store and have no plans at the present time to open one. But after completing that first purchase and realizing that I would never have to make the 22 mile round trip from the small town where I live to the Books A Million store in the next town to buy a book, I was hooked. I've been moving forward in my small online business ever since that moment.
