What will happen if I set a snipe and the 30 day trial period runs out just before the auction ends? Will it snipe for one last time or will it not work due to end of trial period. Thanks

Also. Is the current bid shown an item in myibay my current bid or the current bid on the item in eBay. I have noticed that the bid amount changed on eBay but not on myibay.

Yes, it will snipe.

The current bid does not affect sniping. Please check the following FAQ section for more information:
