Actually, there is no fixed rule for this. My accounts (4 of them :-)) were just opened less than 1 week and I list 2 items per day on each account. I now have about 10 items listed on each of them and so far so ...good > I did not even try to buy anything , just list and start selling ... If you buy cheap things hoping to gain feedbacks, that will flag Ebay. Be innocent, be naive :-) |
