we had a small site update yesterday. We released the following features/bugfixes:
Social buttons on product details page
We removed the old ShareThis buttons and replaced them with the facebook Like button and the Tweet button for twitter.
When you wanted to change the shipping address, this shipping address was not correctly saved, which prevented customers to change their shipping address without creating a new one. This has been fixed.
Earlier this week we also made it possible for users without an account yet to use the discount codes on the checkout page.
