Might not help, but the store looks really good.
For e-commerce, the concept of ‘you get what you way for’ is particularly true. Rapid cart, from what I’ve seen is an amazing solution, but I think @rob has recently had a small family and his time for support isn’t always there.
Anything else, I suspect you’ll be stuck with a monthly fee It’s even worse if you want to sell digital downloads.
I hope you get something sorted .
