I need a SIMPLE shopping cart that my mother can run (really, my mother) on a website. The site is running WordPress, so being integrated with WordPress would be great. We'll probably sell an ebook as well at some point, so integration with e-junkie could be helpful, but not required. What's the best bet? -- Anthony
Check out Market Theme. It's an all inclusive theme with shopping cart capabilities. Very easy to setup, and use. There's also an online demo at the site that you can try out before you buy.
I'm not very knowledgeable when it comes to wordpress but if you don't care about it being integrated with wordpress, ie it could be linked from your wordpress site then I would recommend Shopify. It's one of the more simple carts out there for a new user to master and it sounds like your mom is probably a web newbie.
I'm actually using Wordpress with E-junkie for a new store I recently launched and it has worked pretty good. It's really easy to integrate buttons into Wordpress (just copy and paste the code into a widget/page/post). The only tricky thing might be some of the available features in E-junkie. It's pretty easy to upload a product and get the code to paste on your site, but there are some options I'm still learning what they do.
