Yeah supermarkets have really jacked up the price of Coke lately for some reason but they left Pepsi alone probably because they know Pepsi sucks. I go to a Dollar Tree or a Walmart and get my 2 liter bottles of Coke for $1.30 or even $1 if it's on sale. Definitely stay away from the 20 ounce bottles unless you like getting raped. Coke lover forever and a great stock too.
Hate to say it, where I work, we get a lot of free cokes, as gifts. Get more than I can use at work and at home. Nice perk for my job. Ha, I don't work where you might think, but, at a hospital where free stuff is brought in all the time for us.
