Jeff, it's $6.00 in Canada with $100 coverage - $.65 per $100 for additional up to $5,000.
-- To the US and the rest of the world (hold onto your hat!) it's $11.00 for $100 coverage - no additional coverage available!! So, for an oversize lettermail to the US, the total cost would be $11 + $1.60. Worth it for the security, if it's an expensive item, otherwise ......
Plus applicable postage, of course. Standard size prepaid Express Post is cheaper to the US and for Canada Regional.
