Here is a good read in Shopping Cart Checkout/Abandonment ...

hey dude, check out ecwid shopping cart, its smooth and exactly the opposite of what the article describes, especially 10. Registration Should Be Optional, icq me for example 144949511

Great article. Thanks for sharing Juicy

Ecwid saw that one already looks good , doesn't seem to have a one page checkout though?

asks for shipping address first, email address required, password on same page but optional to make account. It's a basic free shopping cart (paid available) but has a lot of things right.

Auto-detects browsers preferred language so if you can't even read the product description but know what you want to buy, the cart is in your language.

looks good but been using Xcart here for a B2B site we got and though its techinical (editting the tpl files and so on ) it have been really nice to us.

Magento is nice, you need to learn how to skin it but it's fast once you get the hang of it. You can make a nice looking shop with it. They have a free and paid version and an optional mobile setup. You can also do mass csv importing and they have a ton of free and paid modules. You can find anything from blogs to custom delivery and affiliate systems.

Heres an example of a magento shop:

Here's one, lot of broken links but it's an example of how nice it can look.

The downside is for the free version, you obviously wont get much support, but if you or your tech guy knows his/her way around google, you can find most anything you need. Their official support is like 1k an hr though lol but I havent had any issues I haven't been able to find an answer to.

Heres an example, I just googles paxum and magento and found a tutorial on how to build your own payment modules.

I didn't get the impression you needed a cart, but since there are carts being thrown out maybe this will be useful to someone reading this post.

Nice read btw, thanks.
