[quote name='evanft']The Wii package will only be a few pounds, though. I'm thinking Priority mail, as that's what my latest (and best) offer requested. I checked the USPS site, and it looks like I could just use one of those priority mail boxes and get away with paying around $10.[/QUOTE]
If you've already decided on Priority Mail, why don't you just calculate the postage on the USPS website and just kind of guess at the weight?
Just put in a high estimate of 5 pounds, so if it's under, you save money.
Good luck with trying to get it at $10 with Priority Mail with decent packing - Priority Mail got hit hard by the rate changes.
A package that was 3 pounds 6 oz just cost me $12.xx to ship.
