Running orders from Shopify, eBay, Amazon FBM, or Walmart? Default platform shipping rates are convenient — but they are rarely the cheapest option once you count boxes, tape, and the hours you spend packing.
PrepKingz compares major carriers, buys the lowest bookable label from your prepaid CAD wallet, and can handle pick-and-pack at published fulfillment tiers. Use the calculator, then explore channel case studies.

The Shopify label was only $0.65 higher than PrepKingz’s — not a huge gap on its own. Once a mailer, tape, and eight minutes of packing were counted, outsourcing at the published $1.99 Essential fee still came out about $2 cheaper per order.
