I have already invested in equipment, and it adds up even for a BIAB brewer like me. I use ONLY ezcap flip top bottles...... for several reasons, mainly because I like them. They added up to a fair piece of change. My BC mill took a nice bite out of my budget such as it is, two fermenters, airlocks, stock pot, etc.
The good part is that my base malt is costing me 50 cents a pound, though I was given the last 50 pounder. The grain bill adds up to about 2 pounds to the gallon. My most recent batch (2.5 gallons) used 4 pounds of two row $2.00, and half a pound of specialty malts $1.00, an ounce of hops $3.00. Harvested yeast... pennies for the starter, the gas to operate the stove, etc. Total cost probably hit the grand total of $6.50 for 17 half liter bottles of beer. Less than 40 cents a bottle...... call it 50 cents if you will to cover other expenses. In another year or so, I expect to be using my own hops. That'll cut my cost in half almost! I planned on doing some home malting, but the malting barley crop I had my eye on looks like it probably won't yield this year.......... was put in too late, and they are talking about cutting it for hay.
It's NOT about saving money, it's about doing something I want to do. Saving money is part of the challenge though.
