Questions, or something not behaving as described.
A product is not being discounted. Check it carries the
BMSM-ELIGIBLE tag, and that the cart total of tagged products passes
your first tier. Untagged products neither count nor receive the discount.
A code promo and the tiers are both applying. Open the discount and check Combinations. Setting product discounts to combine lets Shopify give each product the better of the two rather than both.
A B2B buyer sees no discount. That is deliberate. Company catalogues carry their own agreed pricing.
Nothing. Your settings live in a metafield on your own store, and this app keeps no database of its own. That is why the customer and shop redaction requests are answered with an acknowledgement: there is no copy of your data to erase.
