i didnt word it exactly right. what I meant is that you have to edit the item on ebay (i usually edit though myebay using mass edit) then in the Price & Duration section of the item you can edit to Automatically decline offers less than X amount.
BUT I just checked and you cannot edit the 'automatically decline offers under x amount' when using mass edit function on my_ebay (least it wouldnt let *me* do it). So, you have to pull up each individual listing one at a time and edit them that way to put it in there *ugh!*
As far as I know auctiva does not yet support the auto-decline function (least I havent found it yet)
