A power seller is an eBay seller who is invited by eBay to participate in the PowerSellers
program after sustaining a gross trading volume above a set cutoff for several months in a row. Power sellers can be identified by a "PowerSeller" logo shown after their eBay User ID in auction listings.
Power sellers enjoy a closer trading relationship with eBay, including specialized tools and increased attention and help with marketing and distribution.
Power sellers must maintain both a high quality feedback profile and constant or growing trading volume in order to remain in the program.
