hi! it would be a great service!
but i have one comment. why does your bidding tool increase the bid to my highest bidding option when it could bid with minimum increase?
that is listing of bids for my item:

Welcome to our forums.

You specified your maximum bid to be 73.00 so if the highest bidder would not bid, then you would get your item for 70.01 + increment only.
But since the other bidder put higher than your max, your bid got automatically increased up to your maximum.
