For some time now Back In Stock has supported two of most popular themes in the Shopify Theme store: Mobilia and Reponsive.
I’m really glad to confirm that this support works with Retina, the latest theme from Out of the Sandbox. Winner of the Shopify design awards Retina was originally used on the jaw dropping Whipping Post site.
For step-by-step instructions on setting up Back In Stock with any of the beautiful Out of the Sandbox themes have a read of the theme integration guide in the help pages. If you need more information just drop an email to email@example.com.
