In certain cases of lost or delayed shipments, USPS offers refunds without the need for an insurance claim. For more information on domestic shipments, refer to USPS's domestic refunds page. For more information on international shipments, refer to USPS's international refunds page.

If your claim is approved, then you receive a check mailed to the address in the USPS online account.

Cubic Pricing with USPS Priority Mail

USPS offers discounted rates on Priority Mail for packages and envelopes that weigh less than 20 pounds and that measure less than 0.5 cubic feet in volume. Consider using Cubic Pricing if you typically send small and heavy products such as weights or coffee beans.

If Shopify calculates a cubic price that's higher than the regular Priority Mail price, then Shopify selects the cheaper rate.

Calculating Cubic Pricing for packages

Use the following formula to calculate the cubic volume of a package. If the amount is less or equal than 0.5 cubic feet, then the package uses cubic rates. All measurements must be in inches.

Length (in inches) x Width (in inches) x Height (in inches) / 1728 = cubic feet

For example, you can apply the formula to a standard adult shoe box:

14" x 8" x 5" / 1728 = 0.4 cubic feet

This package is less than 0.5 cubic feet and qualifies for cubic rates.

Medium (5 lbs) $13.70 $10.33 $7.65 $7.65
Heavy (10 lbs) $26.85 $19.51 $7.65 $7.65
12 in x 9 in x 6 in
Light (1 lbs) $8.00 $7.65 $7.65 $7.65
Medium (5 lbs) $13.70 $10.33 $9.50 $9.50
Heavy (10 lbs) $26.85 $19.51 $9.50 $9.50

Calculating Cubic Pricing for soft-pack and padded envelopes

USPS offers separate Cubic Pricing for soft-pack and padded envelopes. You can add small boxes to an envelope as long as the envelope keeps its flat shape. Expandable envelopes don't qualify for the envelope pricing and need to use Cubic Pricing for packages instead.

Use the following formula to determine if an empty envelope or soft-pack qualifies for Cubic Pricing. If the amount is less than 36 inches, then Cubic Pricing applies.

Length (in inches) + Width (in inches) = Total package length
