Cheap Soda: I got it for about 4 cents a can

First you will need an adapter to use Paintball cylinders with your Sodastream machine.

Check this page for compatibility:

You can get a 24oz cylinder filled at Academy Sport and Outdoors for $4. Sodastream charges $33 for 14 ounces!

Don't even do the math on that one. It's super high.

Now buy a machine:

Finally to start getting the cheapest syrup, buy the boxes at Sam's if you want commercial stuff like Coke Zero.

Shop various stores' clearance section. I recently bought Sodastream Diet Caffeine syrup for ONE DOLLAR at Kroger.

You can also use flavored water enhancer that Aldi sells, or any other concentrated flavor or juice.

Amazon has some Sodastream Sodas as low as $4: http://amzn.to/2mtOj4P


Have fun, and save some serious cash.
