I wrote about this price difference problem (postage purchase price vs MP deducted amount) in a weekly Q&A a few weeks back. Today (Feb 15) I had a deduction from my Managed Payments account for $48.13. I had to do a bit of searching to find out it was originally purchaced Nov. 29, and was originally billed at $47.27. Why is there a delay? Most seem to be going through within the week of purchase. Why the change in amounts? I've done 4 in January, 2 were deducted the same price, 2 were a few cents more. I'm going to stick to Canada Post online from here on.
