The third idea is a page to organise things related to expenditure. On my page, I have 3 tables:
- Wishlist
- Online purchases
- Subscriptions and bills
Putting items in the wishlist first will decrease the likelihood of impulse buying. For each item, I can do first research on the prices and models of the product, list out pros and cons, and think of alternative solutions before buying something new.
Under the table for online purchases, I record what I have purchased recently and the status of the delivery.
The subscriptions and bills table lets me review my subscriptions from time to time to prevent unnecessary spending.
