Probably a broad question but here it goes…
My wife is a painter (canvas not house) and we want to get her a website up.
She wants to show the goods (paintings) and give people the option to order prints and actual paintings.
Its not a great example becuse its only 3 items and they are downloads. But you will see the freedom of creating any layout and then adding the buy buttons. (Or you can use their layout) Also the order look up button is great. There are less expensive ways to do ecommerce within Rapidweaver. But I think cartloom is the slickest. Love the payment box etc. It inspires confidence !
You can try it for free. I found it a joy to use !
Ecwid is another option, you can easily setup your store and integrate it within a RW project, especially if using my Ecwid Stacks. You can highly customize the look of the store to fit your needs. With Ecwid you can select a free plan to start or one of 3 paid plans. If paid yearly you save some money as well.
