Limiting shipping options to expedited only

Topic summary

  • Merchant sells two product types: standard supplies that ship ground only, and frozen items that require Next Day delivery. They want checkout to show only Next Day, and ask how pricing works if a cart mixes frozen and regular items (e.g., Next Day $25 + Ground $6.99 = $32.99).

  • Clarification: They use live carrier rates (real-time rates from FedEx/UPS/USPS), not fixed rates.

  • Guidance provided: Set frozen and standard items in separate shipping profiles (Shopify groupings for products with distinct shipping rules) and enable carrier-calculated rates for both. Shopify will combine rates by summing the least expensive option from each profile at checkout. Reference link to Shopify Help on combined shipping rates is provided.

  • Outcome/status: The method for combining rates is explained; the request to limit checkout to only Next Day—particularly for mixed carts—remains unresolved/undetermined in the discussion.

Ground $6.99

Hi,

Do you have fixed rates or live carrier rates?

we use live rates

Hi @novastables ,

In an ideal scenario, when you set up Frozen and Standard products in separate profiles and enable carrier-calculated rates for both profiles, the charges will be combined.

It’s important to note that since you’re providing distinct services for each profile, the total cost will be the sum of the least expensive option from each profile. For more details, you can refer to this article.
