Depends on the webapp, traffic, etc. I have an EC2 instance and my own domain that runs me a solid $7 a month. It’s just a tiny little web server. If your web app is structured in a way that the client does the processing, your hosting costs can be pretty cheap.

For instance, rather than editing a PDF on a server, if your web app provides all of the tools to edit the PDF in the client’s browser, the server doesn’t need to be particularly robust. Basically it just needs to hand out those tools to the client.

I have a couple from the hip actually, because America has grifting baked into it’s soul. In no particular order:

• MMS (Drinkin’ bleach)
• Crystal healing (most sellers)
• WitchTok kits (TikTok influencers selling expensive spices)
• Brain pills
• Any product peddled by a megachurch (see the Baker bucket for a great example)
• Chiropractors

As more of these come to me, I’ll try to expand the list.

Update: I can’t believe I forgot chiros! They turned themselves into a religion at one point to try to dodge medical licensure laws.
