Can I setup AS to auto delete/remove auctions that go to high?
I would like to start searching ebay for items I want and put auctions as I find them into AS and have AS automatcially remove these if the current bid goes higher than my high bid without me having to do anything.
Thanks in advance for your help.

It will happen automatically. AS will place your snipe, but if the bidding goes over your bid amount, ebay won’t accept the snipe and AS won’t charge you for the snipe since you didn’t win the auction.
