Postage charges I try to split the charge with the customer, but since the post office charges vary depending on the province or state the cost is hard to predict. At present I'm charging
$1 for a thin envelope (under 1/8 ")
$3 for a fat envelope (under 1/2 ")
$5 for a bigger package or for Express delivery in Canada. Express to the US costs about $15 Canadian, or $10 in US funds, and includes
insurance. I will certainly replace anything lost or damaged, and exchange items if you are not happy with them. For special orders I usually send scans in advance, for your approval.
