But not enough to actually make it worth it to deal with customers. Aka you're just not worth it as a customer, sorry.

Yeah, but you only want to pay $2/month. I don't know how you came up with that amount, but it seems too low a price point for anyone to spend the 100s of man-hours to wire it up, not to mention the time spent with customer service. And then there's the marketing, taxes, etc.

You're better off just self-hosting postgres in docker on your own vps for $4-5/month.

Well, the company behind the post offers it for free. They certainly should be able to offer it for 2$?

No. By selling it for $2, they have to deal with the credit card/whatever fee, Wich is typically 2.9%+30 cents, so they're already down from your $2, and then they have to staff customer support to deal with any sort of problems that crop up. Which makes it not worth the < $2 they'd get from everyone in that category.

100 paying customers in that category is still only $200, which isn't even enough for groceries for a family for a month. and for how much hassle?

More hassle free than serving these 100 customers for free.

Especially if you only offer 2 year prepaid options.

Are you really having such a hard time understanding that your 2usd isnt better than a free tier from a business pov?
