I've been running my ecommerce store - www.simplyrangebags.com - off 3DCart for about a year or so. Overall I was quite pleased with their service and offering, then I discovered they wouldn't support Braintree for payment processing. That was a bum deal.
So I started to look around for another cart and came across Goodsie.com. Did a 60 day trial and was quite impressed with their offering for hosted ecommerce. To me they're like a young Shopify and that's a good thing!
Needless to say I switched over this month and am excited to showcase my revamped store as www.simplygunbags.com. I changed the name because I'm now carrying more than just range bags. There's a solid need for sites that sell women's conceal carry bags, etc so I feel a general name change was in order.
I'm excited to see how 2013 will turn out for the store!
