What is the best deal/oz?

Recently, I was sitting at a local brewery sipping on a pint when I saw many people in line purchasing pints & growlers of the same beer. This got me thinking, what is the best deal/oz? Is it a pint, growler, 22oz, or 6 packs? Below is the break down. Sure, there are many variables to consider other than price/oz, bust I'm trying to keep is simple. I'm using prices & packing that are fairly common nationwide.

6 packs (total 72oz's):

• @ $7.00/6pack = .097 cents/oz
• $8.00 = .111/oz
• $9.00 = .125/oz
• $10.00 = .138/oz
• $12.00 = .166/oz

Growler (total 64oz's/half gallon):

• @ $7.50/growler = .117 cents/oz
• $8.00 = .125/oz
• $9.00 = .140/oz
• $10.00 = .156/oz
• $12.00 = .187/oz

22oz bottle:

• @ $3.50/22oz = .159 cents/oz
• $4.00 = .181/oz
• $5.00 = ..227/oz
• $7.00 = .318/oz
• $10.00 = .454/oz

Draft Pints (16oz):

• @ $2.25/16oz = .140 cents/oz (Yes, this does still exist)
  
• $3.50 = .218/oz
• $4.00 = .25/oz
• $5.00 = .312/oz
• $7.00 = .437/oz

6 packs seem to be the best deal when talking about purchasing the same beer in different packages. This was an exercise in numbers and what really is the best deal. Cheers!
