Frequently Asked Questions

How is shipping cost calculated?
Shipping cost depends on billable weight (the greater of actual weight or dimensional weight), distance/zone, service speed, and surcharges. Dimensional weight = (L × W × H) / 139 for UPS/FedEx. Carriers also add fuel surcharges, residential delivery fees, and other accessorials.
What is dimensional weight?
Dimensional weight (DIM weight) estimates a package's weight based on its size. It is calculated as Length × Width × Height / DIM factor (139 for most carriers). If DIM weight exceeds actual weight, you are charged for the DIM weight.
Should I offer free shipping?
Free shipping increases conversion rates by 10-30%. Consider building shipping into product prices, setting a minimum order threshold, or offering free ground shipping only. Calculate the impact on margins before deciding. 75% of consumers expect free shipping.
