Best website template for online store?

[ladybug88]

I'm trying to decide on a design for my ecommerce store. The shop specializes in office supplies, but I'm having trouble deciding which template to choose. I've narrowed it down to these 4:

http://opencartwork.com/floshop2/

http://opencartwork.com/theme46/

http://opencartwork.com/theme45/


Based on these options, which template or theme is most appealing and which one do you think I should choose? Thanks!
