My favourite #WFH money hacks would be:
Staying at home as much as possible (#stayhomestaysafe) which cuts down on my transportation cost.
Staying at home also allows me to do what I enjoy most: cooking! This really helps save a ton of money not just for myself, but for my family members as well - minimising the need/want to dabao/order delivery.
Turning (newfound) hobbies into money saving strategies. For an instance, I used to spend a lot of money on store bought Kombucha but I now brew them my own from Scobys I got for free from friends and ingredients that are low cost!
