I'm moving in two months also and I'm a little scared to really empty my supplement cabinet due to the same reality you just realized. We spend too much on most of this stuff.

I think the problem is that when there is a sale I buy a SHITLOAD so I don't have to keep buying it every month. Hence, I have 20 bottles of Synergy EC from bulknutrition when they were on sale for $5 a pop.
