I have an eBay auction sniping service and users can pay either a percentage of the winning bid of items they win (between 0.5% and 1%) or a fixed monthly rate for unlimited bids (between $6.25 and $12 per month). Sales are fairly low but my prices are significantly higher than some competitors. I was thinking of making a test by offering half my users new significantly lower prices to see if it increases sales and if so offer those same lower prices to all. Does this sound like a good idea? Thanks
