USPS Shipping module no Priority Mail Flat Rate boxes?

-- HikaShop version -- : 4.4.3
-- Joomla version -- : 3.9.0

Hi there! I'm trying to configure shipping, and I need to be able to ship in USPS Priority Mail Small and Medium flat rate boxes. However, they don't seem to be selectable (there are International Small and Medium flat rate boxes, but that won't work). I set up 3 rules based on weight and size to shift between the box sizes (third rule should make shipping free over $100). Unfortunately, Hikashop seems to be adding the prices I set to the Priority Mail prices from the USPS based on shipping zip code rather than using the flat rate prices. Is there any way to either add the flat rate boxes, or fix it so that it doesn't use the standard Priority Mail prices that the USPS is providing based on shipping zip codes?

Hello,

What do you exactly means by "They don't seem to be selectable" ? Can you give us more information about it, about what you actually have and what you want through some screenshots ? So that we can reproduce your issue on our end, thank you.

Kind regards,
Mohamed.

I have the same problem. Attached is picture.

Hello Dana,

I attached a screen shot it has no options for flat rate box shipping.

I'm sorry I think I didn't understood what you wanted to do at first.
There's actually a way to specify that you want to use the Priority Mail Flat rate boxes. To do that, you'll just have to set the "Container" option to "Flat rate boxes".

Kind regards,

Where do I find container option?

Hello,

You'll find it through the configuration page of your USPS shipping method via "Hikashop->System->Shipping methods"

Kind regards,
Mohamed.
