Cash stuffing involves withdrawing your income in cash and allocating it to different categories: 50% for needs, 30% for wants, and 20% for savings 

Some banks offer cash rewards for switching accounts, such as Natwest, HSBC, Royal Bank of Scotland, and Ulster Bank 

The 100 Envelope Challenge requires labeling envelopes with numbers from one to 100, randomly selecting an envelope twice a week, and saving the corresponding amount of money inside 

"Round Ups" are an option offered by many banks, where purchases are rounded up, and the spare change is saved in a separate account 

Rounding up purchases through the week can accumulate savings without much effort, as small amounts add up over time 

Setting a goal of not spending anything for a week, except for essentials like groceries, rent, bills, and necessary travel, is known as the No Spend Challenge 

Cash-based challenges, like the 100 Envelope Challenge, can be an interesting way to save money 

Bank switching can provide an opportunity to receive free money as a cash reward
