Well I live 1/2 a mile from Homeland which sells DICE so I would only grab 10 lbs or so at a time. Would last me several hours.

I think 30 blocks will be the same or more $$ than 30 liters and the LN2 will keep better. I'll call tomorrow and double check on it.
Thanks.

You'll lose a lot of that 30 blocks to evaporation. I would stick with a lower amount. DICE here is $1.39 a lb.
