This is the first time I have used WP e-Commerce and I am impressed.
What I know about coding is just enough to be dangerous, so I am really happy that most tweaking is really easy.
I love that the templates can be moved to your child theme.
I am also impressed with Instinct's support. I purchased the Amazon S3 plugin (which is brilliant) and asked if they could do some work on it so that I could access multiple buckets as I had so many files. The next day it was done.
Paypal worked instantly - no messing around and after purchasing Gold Cart I was in heaven. Makes my life so easy.
Previously I spent over a week trying to get Woocommerce to play nicely - no luck! I even got a coder to try and figure out what my problem was, and all they did was completely lock my website.
I am more than happy to recommend.
