JoyBidder server sniping service submits sniping bids from server, so you don’t need to keep JoyBidder Pro running on your own computer to snipe.
You need both a valid JoyBidder Pro license and pre-paid snipes to use the service.
The service is optional for JoyBidder Pro users. Don’t buy pre-paid snipes if you only want to snipe from desktop.
More info on server sniping.
The pre-paid-snipes credit also allows you to snipe eBay auction from mobile device
