Lots of people have some kind of interest or hobby involving expensive stuff. People involved in that interest or pursuit understand the value of various items of kit or components etc but sometimes that same stuff seems incredibly expensive to people not involved in that hobby. What are some examples of stuff for your hobby that you think is a bargain but you know that people not involved in that pursuit wont understand.
I'll go first with Road Cycling…my hobby. Before taking up cycling I would have thought anything more expensive that the $200 bikes i saw in KMart was ridiculous. I currently ride a bike that cost around $7K and I've bought expensive upgrades on top of that. I spend ages looking at bike stuff and regularly think I've found a bargain because I saw a cool cycling lycra top for $130 etc. Only last week I bought some new cycling shoes for $200 down from about $400 ….. absolute bargain!!!
Other hobbies I imagine would be similar are photography, drones, horses, collecting stuff etc.
I collect old retro PC games predominantly from the 90s. Think original boxed Wolfenstein 3D, Duke Nukem 3D, rare expansions, US exclusives and anything other from the big publishers like Apogee back in the day.
eBay used to be the best place to source the products and there were a lot of overseas sellers too. Now the eBay fees have driven sellers away and those who do sell have their listings sell for big bucks.
A few years ago I scored and original US version factory sealed Spear of Destiny and Wolfenstein 3D for $70. Now I've seen an AU Wolfenstein 3D sell for +$200 in an auction and it wasn't even factory sealed!
Many people would think spending money on old abandonware games is not a bargain but when you can score them cheap and resell for big bucks later on then I think it is a bargain.
