I just finished off the first of my two 500ML jugs of 48mg unflavored from MFS and cracked open the second. Out of curiosity, I checked my order history to find out when I bought that nicotine and discovered it was in February 2012 and that (with a coupon code) that half liter (i.e., all the nicotine I vaped in a year+) cost me less than $30. Of course PG/VG and flavoring would have to be added in, but I'll bet I'm still well under $100/yr for e-liquid. That's like two weeks of cigarettes.
So, thank you MyFreedomSmokes!
