That's great! I can easily afford this hobby [even though I'll sometimes "complain" about being on a fixed income]; I just happen to be frugal. I think it is kind of a fun challenge to keep the cost down. Maybe half of the good taste of DB comes from its being so relatively inexpensive?
For the future - whites, blushes and DB that are to stay in the house I can use dark glass to help keep the cost down. Some folks will hand me back the bottles when they've finished the wine I've given them BUT I WILL NEVER ASK FOR THE BOTTLE BACK.
I'm pretty good about following the admonition of "give expecting nothing in return". But what a thrill and blessing it is when someone expresses a heart felt appreciation for what you've done for or given them.
