Do merchants have the option to add multiple delivery rate options on the checkout page of their websites using ShipBlink?

Yes. ShipBlink allows Shopify and BigCommerce merchants to set and display their own custom shipping rates, flat rates, discounted rates and fallback rates along with the applicable carrier checkout rates fetched by EasyPost in real-time.

Does ShipBlink have any geographical limitations? Are there any countries or continents that aren’t supported by its carriers?
