Site Operation > How do I use "Bid Groups?" to just win one item in a group?
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 eBay snipe in group BidSlammer will cancel bidding for the remaining snipes in that group. This allows you to spread multiple bids around for common snipes -- and get the best price!
Ungrouped auctions do not depend on each other. They will always execute.
The default is to use no group. No-color (white) snipes have no association with each other -- they are won independently.
Grouped auctions will "shut off" once you have won one auction in the group. You will win only ONE auction per group.
