Here's my store, it's not "live" yet as I'm not particularly confident about the store yet.  I've had a play around with other scripts before and always feel probably overly critical of my efforts as they just don't seem to match up to "professional" endeavours.

I think the problem is that without purchasing a decent template, it's a bit difficult to get away from the defaults.

Anyway, have a look: limitededitionphotos.net
