I`ve always just used paypal..it`s probably the most secure method of on-line payment .. it`s really easy to use.. if you have to create an account--well it`s simple....next time you want to order you only have to enter your ID or e mail address you used originally and the transaction is paid immediately [and securely] ..... the last time I paid Toplace for a system it was also via a Pay-pal invoice/request sent to me by e mail..... it`s very convenient.
