I sell my Etsy items for a fixed price that is 50% higher than the starting auction prices I charged when I was on eBay.
Etsy prices are fixed...so, when a collector finds something that he or she really likes, they can just 'buy it now' for the listed price.
On eBay, starting prices are lower, to give room for bidders to give their maximum bids. Some pieces go for less than what the fixed price would have been, while others go much higher.
The fixed prices I have placed on all of my Etsy pieces, are 'average' prices from sales made on both eBay and on Etsy.
I also 'rounded' my Etsy prices to even dollar amounts, to do away with those odd cents I have been using.
