We recently purchased our first 1000ml bottle of nic juice. The prices are quite varied with regards to nicotine percentages (24mg-100mg) so the wild red head (re:wife) broke down the cost versus servings. Personally I thought this was a bit obsessive but thats the accountant in her 
Anyways, we are making 30ml bottles of juice with a 18mg nicotine ratio. The cost of 1000ml bottles ranged from $43-140 depending on the nic percentages. I was amazed by how many bottles (servings) we could make from just one liter. The total bottle figures will vary depending on your nicotine percentages, but I think you'll get the general idea. We used MFS as our supplier.
Basically, with a small investment, the cost per 30ml of DIY juice is under a buck. More money for mods and such!
1000ml Bottle:
24mg $43
36mg $56
48mg $69
60mg $82
100mg $140
Breakdown: (nic% = ml nic juice per 30ml = # of 30ml servings per 1000ml = cost per serving):
24 = 22.5ml = 44 = 97 cents
36 = 15ml = 66 = 85 cents
48 = 11.25ml = 89 = 78 cents
60 = 9ml = 111 = 74 cents
100 = 5.4ml = 185 = 76 cents
