Here is a little trick I discovered for mailing things via the US Postal Service priority mail.
The normal, advertised size for flat-rate envelopes is 12-1/2" x 9-1/2". These are $4.95 to ship anything that fits.
The unadvertised, LEGAL SIZE envelopes also cost $4.95, and are considerably larger at 15" x 9-1/2". You must ask the postal workers behind the desk for these envelopes, as they are usually not on display.
This doesn't sound like a big difference, but i have been amazed at how much more fits inside the legal size. Consider that for shipping a box or thick object inside of an envelope you need a great deal of width to stretch around the sides. For a given object, the small envelope may fit a 6" wide item, and the legal size could fit an item of the same girth 9" wide - a considerable difference, and in my experience, almost always the cheapest way to ship items that will fit.
Great for saving on shipping with eBay!
