To feature an auction on Ebay costs a lot more then normal Ebay listings, but you have to do it on at least one auction listed at a time. Without the featured auctions your listing traffic will be non-existent and cause your other auctions to sell for much less.
A good strategy for featuring an auction is to list a product or service that is very cheap, very popular and you have a lot of them. It is not a good idea to feature a single product for really low, and then try to sell the same product in your store or normal listing for much higher. The buyers will just wait out the featured auction and then see what the item sells for.
Here is a strategy I used a few years ago while selling DVD’s in Ebay
I explained this to my friends and they jumped onto eBay to sell DVD’s and CD’s, but they all had problems, because they never placed featured auctions to drive the traffic to their other Ebay auctions… they were just too stingy, but in the end they didn’t sell anything and ended up wholesaling their lots on Ebay.
