adding along besides boxes cart costs cover extra fees flat handling help hoping item items larger multiple number ordered package packages placing point priority product products putting rate recommend regular requires service setting settings ship shipping single size system testing type types upgrade usps wanted won

Is there a way to have the Cart decide which size box multiple items will ship in?

2 Small items will fit in a USPS Priority Flat Rate Envelope
1 Large item will fit in a USPS Priority Flat Rate Envelope
2+ Small or 1+ Large will ship in a Medium Flat Rate Envelope.

So I set:
The Small item to be a Regular Envelope Packing Capacity=2
The Large item to be a Medium Box, Packing Capacity=2

With Handling Fees @ $0.00 & Packing Fees @ $0.00 (for testing)
1 Small Item is $5.30 - OK
2 Small Items is $6.05 - OK
3 Small Items are $10.60...This is not OK...
I need to cover shipping costs of a Flat Rate Medium Box @ $11.35

Is there a way - besides adding in extra packing and handling fees to cover costs - to have
the Cart "Know" that anything more than 2 Small Items requires a larger USPS Flat Rate Box?

Also, with the settings above
1 Large Item is $5.30 - OK
2 Large Items is $6.05 - which is not okay because it needs to be in a Flat Rate Medium Box @ $11.35 at least

Hoping someone can help point me in the right direction. Thanks,

Hi Mal,

Our service can only use one packaging type for each product, and if those are different packaging types then multiple packages will be used as opposed to placing everything into one of the larger boxes or envelopes.

When setting your packaging capacity I recommend putting the highest number of items that you can reasonably fit in one of the larger packages.

The only packaging type that stacks would be tubes -- our system will assume that anything which is set to fit in a Small Tube will also fit in a Regular or Large Tube. That would work if you had smaller products that you wanted to place in the same package with larger items that might be ordered along with them, but it won't upgrade multiple units of a single product into a larger packaging type on its own.
