Dreams, I also noticed the shipping cost was a bit more than you quoted me, so I sent you the balance. Thanks again!
You didn't have to do that, but I appreciate it. :)
It was my own stupidity - I had the game guides set aside and forgot to put them in your package when I weighed them. It was only when I was doing the final packing that I realized I'd forgotten... and then, the package ended up being over the weight limit for first class int'l (which I didn't even know there was a weight limit), so it had to be sent priority.
Shipping packages is like a "live-and-learn" experience for me, since I don't have a mail scale. :3
