I went to add several snipes, having not been involved in an actual auction on eBay for awhile. After I created my first snipe, I was blocked from creating any further snipes. I was told I had used my one free snipe. What gives? I do not ever recall seeing any such notice before, and I have certainly had more than one snipe going simultaneously before as well.

Hello Susan,
Thank you for your message about the quota. You inquired about this in October, and we replied to that post. It has been this way for a long time. It has been this way for a long time (years). It's possible you were taking advantage of a 'free snipe day' where there isn't a limit on the bids you can add.
I hope this has been answered to your satisfaction, please let me know if I can help with any other questions.
