I've seen many posts on this and no solid answers. I checked with CS and the answer is that it is not possible to have the "Continue Shopping" button show up when there are items in the cart, which is completely inefficient. The agent said she would submit it to the Squarespace developers as a feature request. Our best bet is for everyone to shoot an email to customer support asking to add this feature. The more requests they receive on it, the more they'll consider it necessary. Please shoot them an email so we can get this added sooner than later. Cheers!
