<prompt> Human: I have all of my monthly bills auto paid online, and I use my Chase Freedom with 1 cash back for everything that I buy, even a purchase of a couple dollars. The problem is, Im spending way more than I should be. Ive tried to be more frugal, thinking about each purchase, writing down every purchase, but I need to try something else now. For necessary online purchases, I will just use my debit card and go deposit the same amount in cash at the credit union. This will definitely make me think twice about making online purchases, which are absolutely my biggest problem. If I do this, should I let any extra cash roll over into the next week? Or consider it extra savings and still start the following with the set amount? Or maybe keep it in a separate place that I can use later if I want to splurge, but not automatically add it to my weekly budget for the next week.SO, what do you guys think of this plan? What other suggestions do you have?  <response>: This is known by many as the envelope method where you basically put your money in various envelopes usually for the month and designate how much youll spend on different things - food, gas, entertainment, etc.Then when youre out of money, youre doing buying that thing for the month.If you have extra, you could roll it over to the next week, but Id suggest saving it, maybe let it accumulate and stick it into an IRA or something. Youll thank yourself later.
