A painter finishes one piece and wants to sell it before it leaves the studio. A photographer opens one seat in a workshop. A personal chef puts together six meal kits for the week and wants people to pay before pickup. None of these people need an online store. They need a page that already exists and a button that takes a payment.
Most reach for a real store anyway. Shopify's cheapest plan with an actual storefront runs $39 a month (a bit less if you pay for the year up front), plus a cut of every sale. That's built for someone managing a real catalog: inventory tracking, product variants, an actual cart, shipping rules for every country they don't ship to. It's a lot of software for one painting.
Cantrip has a smaller answer built in. Connect a Stripe account once, in your website's settings, and any post on your site can get a price. Set it, and a "Buy Now" button shows up right there on the page. A visitor clicks it, pays through Stripe's own checkout, and the money lands in your account. There's no plugin to install and no separate monthly bill for cart software you'd use twice a year.
Selling something physical? Turn on shipping collection at the website level and set flat rate options, five max, so a buyer sees a real number at checkout instead of "calculated later." Got one item that costs more to ship than the rest, like a large canvas next to your usual prints? Override the shipping rate on that single post without touching the default for everything else.
Here's the honest limit, because it matters: there's no cart. Every checkout is one item at a time, quantity of one. You can't stack a print and a mug into the same order, and nothing tracks inventory or counts down when something sells out. Running an actual catalog, dozens of items with restocks and variants? This isn't your tool. Go get a real store.
But most solo sellers aren't running a catalog. They're selling three or four things and updating the page by hand every few months. For that, a cart isn't a missing feature. It's a problem you don't actually have yet, and paying $39 a month to manage a problem you don't have is exactly the kind of overpaying-for-complexity this whole company exists to argue against.
