What a fab app and team so far - I was left in the lurch with a cart drawer with shipping progress bar got deleted from Shopify (yes my sales suffered) and these guys have created a really great app to replace it. More features to come, it seems too. Fabulous response to a minor issue when I couldn't work out how to create an offer. Thanks team!
