Selling Packages with PayPal Link

[robinoak]

I cannot figure out how to sell a limited amount of packages via PayPal? Let's say I have 20 packages available (I sell left-over curriculum lesson plans, this usually includes a used book, some papers and a small craft item). The packages all way the same, say 10.8 oz. I want to create a link, that I can send out, where people can pay a flat fee of $20, and from which payment I can then print the shipping labels. When the packages run out, the link will say 'unavailable'. Is this possible? Is it also possible to have each customer pay individual shipping costs?

Thanks!

Then you can export button as button code for website or email link to send to customers.
