Grocery budget myths that waste money

A lot of grocery advice sounds frugal but ends up increasing waste, time, or total spend.

- Buying in bulk is only cheaper if you can actually use the food.
- Coupons often push you toward products you would not buy otherwise.
- Healthy food is not inherently expensive; convenience and branding usually are.
- Chasing tiny discounts across multiple stores can cost more in time and transport than it saves.
