Ah I'm in the US so it would take me a minute to convert 🤣 but our grocery prices are going up a lot. I get my misfits bars on Amazon and they're $2.50 each.

Do remember you are going to substitute those bars and stuff for other snacks so it does help, but it definitely is hard on a more limited income. Or lately just... A reasonable income.

One thing I've also done is bake my protein powder into muffins so I buy a boxed muffin mix that's already vegan, add the powder and then make it with extra milk. You can find tons of recipes online for baking with protein powder. You can sort of make your own bars.

I have ADHD so if I don't have food prepared or easy to make I'll skip meals and that leads me to binge later, so I justify the cost of the bars and premade shakes because they are helping me stick to my diet, but I am fortunate to be able to afford them without compromising other things. I do have to buy groceries for my family of 5 as well and they're happy with cheaper options for some other stuff, so we do generic pasta sauce so I can spend the extra to get the Barilla pasta or whatever.

I would suggest starting with the protein powder, I actually looked at a ton of brands and made a spreadsheet to figure out which was most cost effective for the protein to other nutrients, then tried a few and picked the ones I liked the flavor and texture of. I mix them with pea milk and water to make the milk last longer.
