Hi @areimus,

If you want to use flat rate boxes, there’s no need to add them in the packaging manager. The packages defined there would only be used for the non-flat rate calculation. Checking the flat rate services in the USPS shipping method settings should be enough.

Looks like you have done this and selected a Large Flat Rate box and Medium Flat Rate Box (Top Loading). According to the definitions at https://www.usps.com/ship/priority-mail.htm it’s not possible to pack the items from your cart to either of these boxes – their max lengths are 12″ and 11″ respectively, while your items are 13″ long.

You could select Medium Flat Rate Box (Side Loading), but for this cart combination it would fit only first 3 items, while the fourth one would have to be shipped in a separate package.

If you want to see how WooCommerce Services has packed your items, you can enable Debug in WooCommerce->Status->WooCommerce Services. You will then see the packaging details on your checkout page.

Hi @baldemotions, thanks for writing in!

We might need more information to reproduce and fix this problem. Could you provide the number of items you are trying to ship, their dimensions, services you enabled (Priority Mail, First Class Mail etc.) and packages you have configured (if any)?

Hi kptgreg – it is possible to use the Regional Rate Boxes. Here’s how:
* Navigate to WooCommerce -> Settings -> Connect for WooCommerce -> Packaging Manager
* Expand “USPS Priority Mail Boxes” section and enable the boxes available to you. Save changes
* Navigate back to the label print dialog on the order page, expand the “Packages” section
* Click “Add package” in the menu on the left, select the package type
* Move items to that package
* Click “Save packages”
* You should receive Regional Rate Box price listed as “USPS Priority Mail”
