Short answer: Shopify's built-in shipping discount only makes shipping free. RM: Advanced Free Shipping adds percentage off, a fixed amount off and a capped price, on every Shopify plan. All four types: Free, Percentage, Fixed Amount Off and Fixed Price.
The four discount types
Free: the rate becomes $0.
Percentage: 50% off makes $12.00 into $6.00.
Fixed Amount Off: $5 off makes $12.00 into $7.00. If the amount is more than the rate, the rate becomes free. It never goes below $0.
Fixed Price: $5 makes $12.00 into $5.00. Rates already at $5 or less are left alone, so it never raises a rate.
Examples
Half-price shipping over $50: Cart total Is at least 50, then All shipping rates, Percentage 50.
$10 off express: Choose specific rates, select your express rate, then Fixed Amount Off 10.
Flat $5 shipping over $50: Cart total Is at least 50, then All shipping rates, Fixed Price 5.
A $25 shipping credit: Cheapest shipping rate, Fixed Amount Off 25.
Free Standard and $10 off Express in one discount: in the āÆ menu on Discount setup, choose Add delivery discount.
$10 off over $50, free over $100: create two separate discounts. Customers over $100 get the free one, because Shopify applies the shipping discount that saves the most.
What Shopify does without an app
The free shipping discount only makes rates free.
Live carrier rates can be marked down with a negative adjustment, such as -20%, in Settings ā Shipping and delivery. That discounts everyone, on every order, with no conditions.
Good to know
Fixed amounts and prices are in your store currency and convert for customers paying in other currencies.
At checkout, the discounted rate shows the original price crossed out, with your discount's title or code underneath.
