Cheapskate's guide: The Flashfood app

Steph here. The Flashfood app has saved me a few times when I'm low on funds and don't want to live off of Cup Noodles.

Why it matters: Groceries are still too expensive, at least for me.

Zoom in: The app lets you buy discounted items at local grocery stores (mostly Stop & Shop around Greater Boston).

• I got a box of avocados, an eggplant, peppers, tomatoes and golden potatoes for $5 last week.
• I paid through the app and picked up the food from a fridge inside Stop & Shop.

Pro tip: The veggies are discounted because they're on their way out, so prep them as soon as you get home.
