Yes i had tried to weigh the pro's and con's of encouraging non snipers to snipe on my own items for sale. I actually decided that the percentage of repeat customers is quite low (due to selling a wide variety of items instead of being a dealer just selling lots of the same thing). low enough to take the risk and advertise for A/S to gain free snipes or $$$.
But alas, i'm still no nearer to the answers i require. Can support tell me how i can advertise A/S on my end of auction emails???
