I was running into Costco for a few things and saw they have some back to school stuff, incl. large wall maps (laminated) for 6.50! They have a United States map, world map (that's the one we got), and several maps with different illustrations (like what is happening in each state/continent, etc. Maps like these are around $25 at Lakeshore Learning. I'm going to put it up on the wall in the playroom.
