Advanced Shipping Rules

Excellent app for automatically determining if an address is residential or commercial, and offering the appropriate rates with no customer input. Savings from this feature alone will pay for the app. We reported a minor bug that prevented a shipping option from displaying, and the developer responded quickly with a fix. An apparent limitation is that shipping methods cannot be reordered and the default method cannot be changed, but it turns out this is a limitation of the Shopify checkout page, not the Advanced Shipping Rules app. This one's a wise purchase for sure.
