To manually top up your account, with a one off payment, you can place a manual deposit. This can come from any accepted source. It will need to be verified in the case of a new source. This option allows advertisers to only top up their accounts when they wish, but may lead to interruptions in traffic whilst an account has no available funds. You should select Manual deposit from the Funding & Payments menu. The default selected is $1000, you can select any of the other popular amounts, or choose to manually type in how much you wish to deposit, with a $100 minimum.
