If you are getting shipping rate at checkout that does not have the same name as the shipping rate you setup in Better Shipping. Then you may have a default shopify shipping rate setup in your ShopifyAdmin->Settings->Shipping and delivery->General->Manage.
On the ShopifyAdmin->Settings->Shipping and delivery->General->Manage, under the Shipping Zones section in the relevant shipping zone (E.g. "Domestic"), you can check which shipping services are installed for the shipping zone. If you do not see the "Better Shipping App rate estimates" service under the shipping zone, then the Better Shipping service is not installed.
If this is happening then it may be one of the problems already described above:
- No shipping services installed in your Shopify Admin
- Carrier calculated shipping feature is not installed in your store
- How to use Test Mode
- Zip/Post code restrictions on your store
- No shipping rates in Better Shipping
Please note, that once you have the "Better Shipping App rate estimates" service installed, if you have other shipping services in your shipping zone (such as the default Shopify shipping rate, or another app or carrier service), then both rates will appear at checkout. This will give your customers the option to choose between them. If you want to use Better Shipping exclusively, so the customers must choose the Better Shipping rate, then you will have to delete all of the other services in the shipping zones.
As always, if you still can't get the app to work the way you need to, please don't hesitate to email us at firstname.lastname@example.org so we can help you out!
