Best Advice Ever I Copied Form LurkeyLou With His Permission
“if you depend on your eBay income at all, you'll want to continue selling there while you create an exit strategy to establish yourself independent of eBay.
I don't recommend starting with finding "the best" auction site beyond eBay. I recommend setting up a store for yourself as a first step.
PSU offers an inexpensive option for the intermediate to advanced tech type. BuyItSellIt.com offers a free option for the non-tech type. Yahoo offers stores, not the easiest to set up but millions use them. ZenCart and OSCommerce are free for the more advanced tech type.
Once you get set up I recommend using "alternative" venues for additional M&P. The reason is you're going to work 10X harder for 1/10th of the sales (if you're lucky) you got on eBay with the "alternative" venues. The "alternative" venues do little to no advertising; traffic is much lower than eBay.
Folks will tell you this venue or that venue is better for this reason or that reason but the majorities seem to have between a 1% and 3% sell through rate. Essentially, if all the sales for the entire venue were counted most would not qualify as a Silver PowerSeller on eBay. There are exceptions but nothing consistent. A big-ticket item here and there might make the numbers look better for a month but the stats are a bumpy ride at best.
The alternative to eBay on an income replacing level doesn't exist unless you're willing to do the work that the fees you pay to eBay pay for, the marketing and promotions (M&P) - getting buyers to your goods. If you're willing to do the work, then I recommend investing in yourself first and then using the "alternative" venues as a means to increase your own M&P.
If you start by using venues first, you're going to invest a lot of time trying to make as many sales as most sellers make by accident on eBay...your own store will be hard going, too, but you won't be at the mercy of anyone elses changing business plan or some owner pulling the plug in the middle of the night without warning.”
