BS ‑ Better Shipping 89 reviews · 4.61★ · fair evidence
It does the per-product and per-postcode rate rules Shopify can't, and multi-year users stay — but it's sold on the support team configuring it for you, two reviewers say the developer pressured them over their reviews, and only three reviews exist from the past year.
Most common complaint: Hard to configure alone — most successful setups happened because support did it, and several people gave up before that (12 reviews, steady).
