I am finding that there is a huge discrepancy between the shipping costs that eBay calculates for Small Packet Air and what Canada Post's calculator states that the costs will be.
I'm selling buttons. My parcels are 22 cm x 17 cm x 5 cm and weigh 40 grams. Canada Post's calculator states that the cost to ship to France by SPA will be CD $9.37, but the calculator in my listings states that it will be CD $18.63. That's a whopping $9.26 difference.
There is also a discrepancy in the figures given for Small Packet Air to the US. Ebay's is CD $10.60 and Canada Post's is CD $8.03. That's a $2.57 difference.
Can anyone enlighten me as to why this is happening? I've been using these calculators for years and I don't think I'm making a mistake that is causing these discrepancies, but anything is possible. Thanks for your help. Laurie.
