In order of value but without the price:
1. My house
2. My Wedding + Honeymoon (does that count as a single purchase)
3. Investments (if counted together)
4. Engagement ring
5. A Holiday (multiple)
I tend not to spend much on things like TV's, computers or even cars (yet).
At home I have 1 desktop and 2 laptops, none of which were expensive.
Desktop is an i7-3770, 32GB RAM, 256GB SSD + 2x17" TFT Monitors @ US$1,050
Laptop 1 is a Lenovo ThinkPad AMD Dual Core (don't even remember/car about clock speed) with 4GB RAM and 500GB HDD @$450 (purchased in 2010)
Laptop 2 is a Lenovo IdeaPad Yoga 11 with ARM processor, 2GB RAM 64GB SSD, running Windows RT @ $485 (purchased in in 2013)
