How can I cope with rising prices with reduced income?

Well, I can suggest you a few tips that I am following in the last few months.

Create a budget based on your reduced income
Buy generic items or opt for store brands as they are less pricey
Buy when the sale offers are there

Have you got your stimulus paycheck? Use it wisely.
To add on some tips what David has already mentioned:
Follow a minimalist lifestyle
Focus on enjoying other things in life that you can do without spending - Instead of browsing through online shopping portals, nurture a hobby

Hi Hoggerd! If you are unable to cope up with the rising prices, it's time to stretch your budget to some extent. Besides, if possible opt for a side hustle to generate more income. I would suggest you make your passion as your side hustle. By doing so, you feel good during this situation and earn money as well.
