I'm busy price-checking sheets for my brother in Iraq this morning! I'm trying to resist my urge to hop in the car and go to Tuesday Morning in person. Overstock is having a $2 shipping sale.
While I'm deciphering which companies ship to APO addresses, I thought I'd refer you to an excellent site for frugal moms, www.momadvice.com. Amy is a young mom who's put together a terrific collection of articles and tips, all in a very pretty package.
I particularly liked her breakdown of warehouse shopping here. Enjoy!
