If you are active on eBay when the auction ends, eBay can get confused because EZsniper is trying to access it via your account at the same time. This may result in your bid not being made.
No difference with an automatic relaunch in eBay, and difficulty following the auction and to correct the amount according to the trend of the auction.
Automatic renewal subscription.
Bid Groups let you group similar auctions together, and win only one eBay snipe per group. Each group will execute only one eBay snipe. Once you win an item in a group, BidSlammer will cancel bidding for the remaining snipes in that group. This allows you to spread multiple bids around for common snipes to get the best price.
This program is constantly having issues so that bids often do not place at all. Sending an email to them gets "server unavailable" reply. Used to be a decent program but not anymore.
The bidding happens via a remote, privately-controlled server. Even though you don't give eBay credentials and remote servers are typically more reliable than home connection, but for some users it may be a downside.
All communication channels are encrypted with the latest SSL standards. bidbag does not save my eBay data. The service officially has access to the eBay API and has been approved by eBay. Only a token generated by eBay is saved. This token is used to communicate with the eBay servers.
