I have a house already, which I've overpaid on quite well, so I am treating myself to a few things, some tech and some stuff for the house.
Recently bought:
55" LG OLED TV
Xbox One S and a couple of 4K blurays.
iRobot Braava 320 floor mopping robot
Sideboard for my lounge
Coat rack for my hallway
New plates and bowls
Some laundry basket cube things
Philips Hue stuff to go with my existing setup; hue dimmer switch, 2 x motion sensor, iris lamp, and 5 x white ambiance bulbs
I need more things still... I am largely looking at stuff for the house really, as I like to get stuff that is useful and lasts a while if I can.
Need a new rug for the lounge, considering getting a small "phone" table for the hallway, want at least 1 hue go lamp at the right price. Biggest thing I am considering buying is probably a car though, as mine is getting a little old. I may defer that though and just overpay the mortgage a bit and keep my current car going longer if I can.
