I know feel your pain SOH,first time i bought way too much as well,the dry ice company packages it in approx 2 lb blocks for about 2$ per block but i came home with 10 blocks,a little goes a long way!! Now i just buy a couple blocks and still end up throwing it when im done,i tried saving it in the freezer too,and had the powder/frost all over everything in the freezer,...for anybody new at trying this,keep a couple things in mind.First is,di has a temp of -198.3 and it could frost burn your skin if handed carelessly,,second,from what i read,it could also kill the freezer motor of a regular/household freezer cause the super cold temps it creates if stored in there,,Last tip is use 73,120,then 160 or 220 screens separately,and dont shake for too long cause di turns everything but stems to dust and causes plant matter to get the screen( gotta mention,i only do bud run)
