Due to the increased cost of the special types of material we use (shot up 15 percent!), freight, labor, and incrasing business costs in general (state unemployment insurance tax tripled!), we will be increasing prices for the bags by 10% on Oct 25, 2010 - right after the DC Green Festival. So the cost of one large bag will go from $34.95 to $38.45. For 3 large bags, it be from $90 to $99. For the medium bag, it will be from $25.95 to $28.55 for one and from $66 to $72.60 for 3.
