currently testing out YSM and so far I love the interface and its ease but having funds in the account prior to my ads to be shown is a bad way of billing. I think billing after clicks is better, the way adwords does it I wonder if there is an option to adjust this - because I think I should be able to pay every month or at a cap not fund the account first then show my ads anyone have similar issues?
if the amount is not sufficient for 3 days they deduct from your credit card. convert your account to prepaid by contacting customer support
