I plan to allow people who visit the store front to pay their monthly dues using the store. My problem is different people pay different rates. Really do not want to create a product for each item with each possible payment amount. Was looking for any advice from those who may have done something like this.

My plan is to do something like make this a free item and then have a Payment attribute where the person will put in the amount of their monthly payment. Will only use credit card payment type so can check this and charge the right amount manually.

Thanks
John
