TheTerrainGuy.com is having a sale on their EASY TERRAIN tile sets.
From their announcement:
All of our EASY TERRAIN tile sets are on sale for $10 off through the end of June.
EASY TERRAIN tiles are durable, versatile and portable. These interlocking tiles are made from high density foam rubber. Unlike traditional styrofoam terrain, these tiles will not break, chip or flake.
This terrain system uses two-foot square and one-foot square tiles that are completely compatible, this creates more options for game table sizes.
These tiles can be assembled and disassembled quickly. Also available are road tiles in four different road widths. Our PIN-A-TREE trees may be used with these tiles, and the color schemes match our dense rubber hills.
