If you sell at least 40 items per month it pays for itself, and after that it's all savings because you don't have to pay the $1 fee per item. You also need it to be able to list new items.
You also need to be able to LAST for 1 month ha. I would like to see some people chime with experiences with this type of account and experiences with listing new items.
i never had my card charged ? They take always the money from the balance
thats if you have a neg balance. Normally when you start with a merchant account, your amazon balance is -39.99 or something like that from the start. So if you are suspended within a week or month and didnt make enough sales to cover you, your card will charged
