FAQ

Which fees are included?

Only monthly base storage fees are included. Aged inventory, low inventory-level, overage or other surcharges are not included.

Size tiers are generally matched from top to bottom. After a product enters standard or oversize classes, the matching fulfillment, storage or removal rate table is used.
Length + girth = longest side + 2 x (median side + shortest side).
