I put in snipe at 388.88, item closed at 162.5
And no bids were placed on my behalf

Hello Randy,
Thank you for your question about Bid Groups. By definition, any items you place in a Bid Group will be turned off as soon as you win an item in that group. You can tell them apart: The "win in group" icon is slightly different than the "win" icon. (The smiley face is winking.)
Here is our help page on that subject: https://bidslammer.com/help/bid_groups
Please let us know if you have any other questions. We welcome any other questions that you may have.
