In our account every pack coupon was worth about 12% of its minimum freight, so on any single parcel the 40% coupon saves more.
Which coupon to use when
- Put your biggest parcel on the 40% coupon. It’s one coupon, and a percentage saves the most on the highest freight.
- Use pack coupons on later parcels. Pick the largest coupon whose minimum freight your parcel beats.
- Watch the date. The coupons are valid for 30 days after you redeem them, so plan your parcels inside that window.
Grouping items into one bigger parcel is often cheaper overall; our LitBuy shipping guide explains why.
How the calculator works
- Coupon values and minimum freights come from the coupons credited to our new account on 30 September 2026. The pack contains more coupons than the twelve we list; see the full list and screenshots.
- It compares one coupon per parcel. LitBuy shows which coupons you can select when you pay for shipping.
- “Freight over $X” is treated as strictly greater than $X, as LitBuy displays it.
