I believe Autoship is the name of a program offered by SFI Marketing at www.sixfigureincome.com. Under this program, SFI members purchase certain products (vitamins, etc.) each month and earn a commission from every downline who also buys these products. It is a common Multi-level-marketing strategy. I feel it is best not to translate it into Chinese but rather leave it in English. For your reference only, of course.

Autoship means a preset monthly order that is automatically charged and delivered. Some pyramid or multi-level marketing companies makes this a prerequisite for the consumer (potential multi-level-builder)to enjoy the nice discounts and/or commissions generated therefrom.

So I translated as "$200 U.S. dollars of guarenteed purchases with a fixed schedule(automatic shipping or 'autoship')". This is a translation that is in the target language with the original word used in parenthesis.

If you want the chinese characters, I can email this to you in classical or simplified characters.
