RapidWeaver makes it ridiculously easy to create stunning websites on your Mac. If you'd like to add a store to your RapidWeaver site, you can use Ecwid shopping cart.
How to add an online store (shopping cart) to your RapidWeaver site
1. If you don't have an Ecwid account yet, feel free to create it here. It's free (paid accounts are also available though). Then log in to your control panel and copy the integration code from the "Dashboard" page. Save it somewhere nearby, you will need it pretty soon.
2. Launch RapidWeaver and press the "Add Page" button.
Select the "HTML Code" page type.
And name your page.
3. Then insert your Ecwid integration code to this page and save the changes.
4. Your store is ready!
