what's the best option to save money on everyday expenses? 
There is a saying in business: what gets measured gets done. Track every expense you make. Later, look over what you have learned. If 5% of your total budget is going to something frivolous, maybe you could halve it? If 1% or 0.1% is going to that frivolous expense, there's not much to be gained even by eliminating it. If you spend $200/mo on coffees, dropping those will help. If you spend $10/mo on coffees, you need to look elsewhere for your big savings. Have a target: I want to put $X into savings each month. Therefore I can only spend $Y. What do you have to change about last month's spending patterns to get down to $Y? Where are the easy targets for you? They will be different than the easy targets for me. What absolutely cannot change for you? Once you know the costs of what you're doing, you will know where it's possible to save, and where it's "worth it" to economize.
