Yeah their minimum is $10, which for me, I can only justify if I daily your project, or use it frequently. I love the site, but I don't use it nearly enough to justify this cost. $5 I might forget about. There's a site I rarely use that I pay $3.99 for, because its <= $5.

I'm guessing fees make it not worthwhile, maybe they should negotiate lowered fees from their payment service, or figure out someone else who would give them drastically lower fee rates.
