This guide explains how automatic shipping works when you accept Thryft Ship Payments — including flat rate, tiered (per-item) shipping, domestic vs international rules, max shipping caps, free shipping thresholds, local pickup, and manual shipping overrides.
If you accept Thryft Ship Payments, you can optionally enable automatic shipping.
That means when you create an order, you only need to enter:
Then Thryft Ship automatically applies shipping at checkout based on the rules you set.
Adding items + setting the amount owed for the items.
Applying shipping automatically at checkout (domestic/international, per-item rules, caps, and free shipping).
Once enabled, you’ll see a notice on each order showing whether shipping will be auto-calculated at checkout.
Toggle this setting on to automatically calculated shipping.
Flat rate shipping charges a set shipping amount for the order.
Example: Flat rate domestic shipping = $8
Customer buys an item for $40 → checkout total becomes $48.
Good to know: Thryft Ship tracks whether shipping was already paid for that order, so customers won’t be double-charged shipping on later checkouts for the same order.
For example: if a customer buys item(s) from you for $40, we automatically add your flat rate shipping cost of $8. The customer checks out for $48. If a customer then later adds to that same order and buys another item(s) for $30, we know that flat rate shipping was already applied for that order and DO NOT charge for shipping again. So, that customer will only checkout for $30.
Tiered shipping on Thryft Ship is based on number of items (not order total). A common setup is a base amount + an extra amount per additional item.
Example rule:
How it calculates:
Multi-checkout aware: If a customer checks out multiple times toward the same order, Thryft Ship will apply shipping correctly based on what’s already been paid (so shipping doesn’t “restart” from scratch).
You can set a maximum shipping amount so shipping never exceeds a number you choose.
Example: Max shipping cap = $12
If tiered shipping would calculate above $12, shipping stops at $12.
This is especially helpful for bundle-heavy sellers so shipping stays fair and predictable.
You can set different shipping rules for different destinations.
Applies when the customer’s address is in the United States.
Applies when the address is international (e.g., Canada or Australia).
Automatic: Thryft Ship applies the correct rules based on the address entered at checkout — no manual selection needed.
A free shipping threshold removes shipping when the customer’s total amount owed during checkout meets or exceeds the threshold you set.
Example: Free shipping threshold = $100
If the checkout total owed is $100+ → shipping is removed.
💡 Note: Free shipping only triggers if the total amount owed during checkout meets or exceeds the threshold. It does not apply retroactively to already paid orders — only the current visit’s items count toward the threshold.
Example A (two separate checkouts):
Threshold = $100
Because neither checkout individually reached $100, free shipping won’t apply.
Example B (one checkout meets threshold):
Threshold = $100
If the customer keeps adding purchases to that same open order, free shipping remains applied for that order.
If a customer selects Local Pickup, shipping will not apply.
When Local Pickup is selected:
The order total will reflect items only.
Automatic shipping is optional. If you prefer to charge a custom shipping amount for a specific order, you can add shipping manually as its own line item.
Step-by-step guide:
Important: If automatic shipping is enabled, manually adding or editing a shipping amount will turn off automatic shipping for that order.
In other words: if you do nothing, shipping will calculate automatically at checkout. If you add your own shipping line item, your manual amount overrides automatic calculation (for that order only).
