Yes, I am having a bit of trouble with Squarespace's shipping options. I need to be able to ship internationally and the "flat rate" or "weight" option is way to inaccurate for my business. I signed up to an Advanced Commerce Plan thinking the "Carrier Calculated Shipping" would include int. shipping rates. It does NOT. Squarespace, this should be your number one priority to set up. Please consider working closer with ShipStation, maybe have it built right into the Advanced Commerce plan, so you don't even need to leave the site. For Squarespace to advance, you need real time carrier calculated shipping for international order built in to the advanced plan. You guys are doing a great job and you're smart, so get on with it. Thanks.
