This rises a question: is this CC theme developing somehow extra difficult, or is there some other reasons?
I only found out a handful of themes, and to be honest, not very classy. Not even useful. This resembles the situation with LiteCart platform which have none theme to offer either. Unbelievable.
I'm currently migrating my WP + WooCommerce shop. My choices are now CubeCart and OpenCart. I'd prefer CC, but this theme issue blocks it. OC development offers hundreds of nice themes, both free and commercial. Too bad.
