It gives options for ordering by phone, check, echeck, fax, money order, purchase order and wire transfer.
It will integrate with real time shipping estimates from USPS, UPS, FedEx and Australia Post. (but you have to create separate accounts with each of those companies and jump through a couple of hoops)
You can also define your own shipping rates on a per item or per order basis, or by weight, or as a percentage of the price.
It produces a nice invoice for the customer and emails order notifications to both the seller and customer.
You can have multiple categories.
You can define your own sales tax rules and have destination based or source based tax rules.
It has a nice css based layout so it is relatively easy to customize, but you probably won't have to.
You can configure the catalog to display as tiles, grid or list (with images of course).
It is all Ajax driven so it is pretty fast.
You can change the product thumbnail sizes.
You can define your products in a spreadsheet, export to csv and import them into the cart (just don't import columns that have no data!)
It is really a pleasure to work with. The FAQ says they may offer a paid service in the future, but the free version will always be free. If you've been looking around for a nice shopping cart, check this one out.
There is a small css error in modules/mod_ccsignup/tmpl/default.php (style="margin-bottom:2")- it should be margin-bottom:2px. But that does not impact the usability in any way.
Thanks for the input. I will log the bug and have it fixed in the next release. - Cheers!
