Hello Andrew,
Thank you for your question about your snipes. You have been putting your items in 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.
Here is our help page on that subject:
https://bidslammer.com/help/bid_groups
In short, it sounds like you have been using groups as folders. But groups are not folders.
Please let us know if you have any other questions. We welcome any other questions that you may have.
