nopTools has released Shipping Director 1.14 for NopCommerce 3.20
You can download it from the Download Trial link on its product page on www.noptools.com.
I'll be blogging about it shortly. I'll also blog about nopCommerce 3.20's new "Use Warehouse Location" setting, a similar setting added to Shipping Director, and how Shipping Director can even allow one to set up drop shipping from Vendors when they use different rate calculation methods (e.g. Vendor1 uses UPS, and Vendor2 uses FedEx), and combine the rates with generic names - "Ground", "Overnight", "2nd Day".
(Payment Director should be ready tomorrow :)
