I do a combination of coupons, rebates, biking for store dollars, shopping at small ethnic markets, and not being squeamish about buying manager's markdowns. I've tracked groceries for over a year now, logging every receipt. This includes food, beverages except booze, all cleaning supplies, toilet paper, shampoo, soap, toothpaste, and OTC meds, including stupid pricey prevacid or the generic version. For the last 15 months, I've spent a total of $1389, or an average of $92.43 per month for two adults ($1.54 per day per person).
So yes, I think it's worth it!
Today is a pretty typical diet-wise. Breakfast was coffee with a splash of a vanilla protein smoothie instead of cream, a peanut butter and date syrup sandwich, and oatmeal. Lunch was a smoothie made from a cantaloupe (yes, I ate the whole melon!), fresh kale, coconut milk, and flax seeds. I had a snack of peanuts, then another of cereal, then another of biscuits (yikes!) but in my defense, I've biked over 2000 miles this year so far, I eat a lot and don't gain weight because of that. :)
Dinner is going to be pasta with an herb dressing with leftover onion/sausage stuff that I cooked when I made pizza last night, and a side salad with lettuce (not the iceberg shit, real lettuce), goat cheese, a chopped apple and pecans.
My breakout for June:
Out of pocket costs (what I paid at the register): $140.24
What I saved from coupons: $76.50
What I saved from markdowns: $75.65 (an estimate - it's hard to tell if you get a case of loose produce what the full cost would have been)
What I saved from biking: 32.29
Rebates: $44.13
final cost: $91.11
You be surprised at the deals you can get for real food. Everything from milk (cow, almond, coconut), eggs, chia seeds, fresh produce, etc. Also once I found $20 on the ground while biking to the store to get a free (after coupons and rebates) $30 bottle of vodka, that was an exciting day!
The government figures that for a couple our age, we should be spending between about $4500 - $8500 per year, depending if we are thrifty or liberal. We spent $1100 in the last year. Saving $3-7k seems worth a fair amount of time to me.
