By default, products have a shipping class set to No shipping class.
The way we’ve set up shipping, items with no shipping class will use the no shipping class rates in your shipping methods.
Here’s the rate table for what we just set up:
| Shipping Class | Standard | Expedited | Local Pickup |
|---|---|---|---|
| No shipping class | $15 | $25 | $2 |
| Heavy | $25 | $35 | $2 |
| Free Shipping | $0 | $10 | $2 |
When checking out, your customer will choose the shipping method. For example, a product with No shipping class (default) will show 3 options for the customer to select from: Standard ($15), Expedited ($25), Local Pickup ($2).
As of 2025, the flat rate shipping cost for USPS is $15.50 for the medium flat rate box. If you have an additional $3.00 in shipping materials, your shipping table may look like this:
