I have been doing this for ages, having had 40 free available each month and had over a hundred listings on the go no problems, but this month there was a discrepency of 11 available listings between my count and ebay 40 free. when i checked the item numbers they were random listings from february and june that had taken up those extra free listings.... i have been on to the help all morning and all they could tell me was that whatever you don't sell rolls over to make up the numbers in your free 40 the next month. i tried to explain if that was the fact, how was i able to list a full 40 each month for the last 4 months, i shouldn't have had any free listings available if this was the case, let alone these random older listings using space in August.... they do my head in sometimes. just deleted a heap of ending soon items just to see how that goes.
