For FedEx Envelopes:
For weights up to 10 lbs, all the products will be packed in a single envelope. For weights above 10 lbs, the shipping will be calculated based on FedEx Standard Rates.

For all other Packages:
For weights up to 50 lbs, all products will be packed in a single box. Above 50 lbs, the shipping will be calculated based on FedEx Standard Rates.
