For me it was Badminton. You can start off with cheap $15 rackets and plastic shuttlecocks. Now my racket is $260 and I play with feather shuttlecocks which are about $2 a piece and only last a few rallies.

Instant (analog) photography and collecting pins and buttons. Turns out film is expensive and buying pins are expensive. Started out with friends giving me pins to stick on my bag and now I have close to hundred pins on my pin wall. At least they look pretty rad.

Collecting vinyl records. I started 10 years ago when you could get lots of records for 3-5$ per record. Now everyone is crazy about collecting and they can cost 40-50$. Was a great investment if I sell them. But I enjoyed collecting them regardless of value.

Collecting military surplus/old random military shit. Helmets, great coats, radios, a field phone, ww2 machete. Ya get the idea.

Running as soon as I discovered the Runningshowgeeks subreddit.

EDC (everyday carry) this can include pen, notebook, knife, phone, fidget, etc. my most expensive piece that is in my current rotation is my fidget clicker in full brass from unquiet hands. that one chunk of metal and magnets cost me $130

Playstation 4. Huge money went into buying discs and digital games.
