Advice needed: how to set up online payments for direct-sale books

Hey, everybody,

I’m not exactly interested in setting up an online store where I have to package and mail the books myself, but I do want to be able to do so on a small scale where I can offer temporary sales that are a much better buy than the Amazon price. I would advertize these sales in my newsletter, FB pages, and paid advertizing in homeschool newsletters.

Does anyone have any ideas about how to set this up and receive payments online? I have Square but haven’t been able to figure out a way to make it work for online sales. Perhaps there are online store options somewhere that would work for a small-scale business. I would be willing to pay at a rather high rate on a per-transaction basis (like as much as 30 cents per transaction plus a percentage of the sale) but would not want to have a monthly fee since my business would probably not justify this expense.

I would very much appreciate any ideas on this.

Thank you,

Holli
