I'm in need of setting up an ecommerce shopping cart on my website. My web host provides OScommerce, ZenCart, and Cube Cart. It's not going to be real big - maybe a dozen or so items. Payments through PayPal and cash, so I need to be able to interrupt the transaction for cash accepted without forcing an on-line payment screen. And room for discount codes.
My biggest concern is that it be accessible on a mobile platform. I'm barely familiar with coding for a PC; my understanding of mobile is zero! I know I'll have an Android phone, so I want it to work there. I presume that if it works for me, then it'll work on iPhone and WinMobile, too. Don't know about "dumb phone" mobile web?
Where would I need to go for the information I need to make a decision? For that matter, _what are_ the decisions I'll need to make?!
