Today, I had mailed a package at USPS requesting my package to be mailed Airmal Parcel Post to Canada. She rang everything up and posted the stickers all over the package. The total came to $4.00, I thought it was extremelycheap sending from Houston to Canada but didnt think anything of it. When i got home I looed at the USPS website and it turns out that Airmail Parcel post for a package was $14.00 and Airmal Parcel Post for a letter was $4.00. So I assume I was charged letter postage. Will my package still be sent? I am worried!
