Yes I do. I plan for my monthly expenses and move accordingly. 

I use both cash and credit card but mostly I prefer to pay cash.

I think planning or budgeting is very important because without budget I can’t save anything.

List down the expense you want to make during the month with estimated amounts.
Check your list and reassess if you really need these things to buy.
When you go for shopping make a list of things you need to buy and then restrict to that list.
Leave some amount for contingencies.
