Reseller Ops
Shipping Thrift Flips With Canada Post Without Losing Your Margin
Share to
Canadian resellers lose more margin to shipping surprises than almost any other line item—and most pricing guides written for the US market don’t help.
Domestic rates aren’t as forgiving as USPS
Canada Post’s domestic parcel rates run higher than comparable USPS options, so a shipping estimate copied from a US guide will consistently undercharge.
Cross-border shipping needs its own math
Selling into the US from Canada means factoring in customs paperwork and currency conversion on top of the base postage—build it into price, not into surprise.
Package weight assumptions cost real money
Rounding up to the next weight bracket before you ship, not after a scale surprises you at the counter, keeps your margin intact on borderline items.
Flat-rate options exist but aren’t always cheaper
Compare flat-rate boxes against calculated shipping for your specific item before defaulting to whichever feels simpler—the cheaper option changes by weight and distance.
ThreadFlip’s comps already account for the reality that a listing price needs room for shipping, so you’re pricing an item to actually profit once postage is paid, not just to list it.
