We definitely eat in season produce but we still spend alot of money on it. Plus, you get really tired of the same things for months at a time. For us, fruit is really expensive too. At the local grocery store apples run $1.39 a pound, oranges are 3/$1.99 or 5/1.99 at best, pears are about $1.29. We are enjoying the first crop of corn here, you can get 6 ears for $1.00 at the market.
We typically go the farmer's market for produce and the grocery store for perishables, grocery items, cleaning supplies and protein (chix, fish, some red meat). Fruits--I eat 1-2 servings a day at most, same for DH, DS eats 2-3 servings. Veggies, I eat 5-6 servings, DH about 4-5 and DS about 3-5 per day so it definitely adds up.
Our store's big loss leaders are milk $1.59/gallon and eggs (I'm allergic to them), peanut butter (ok for DS & DH, but again-allergic) and things like hot dogs or bologna. The cheapest chicken breasts I can find are $1.99 pound (on sale & that doesn't happen often) and the cheapest fish is from the home delivery company called Schwans-they are cheaper than the local fishmonger.
Our biggest market (Wegman's) has some competition from SuperWalMart (where I sometimes go for cleaning supplies and some grocery items, but get frustrated waiting in the lines that have been so long it is ridiculous--I mean 20 mins in line to save $2.00??) The only other competition is a store called Tops & they have horrible produce, a small & somewhat unkept store & high prices (IMO) too. I'm even tried to shop a local Big M market (small locally owned store) but they are 10-15 mins away so I'm not saving much driving there.
They are going to build an Aldi's near me (the closest one is 15-20 mins away) and I have heard that they offer some good deals if you know what you are buying/spending at other stores for the same products.
If you think my family's grocery budget is bad, don't even ask what I spend for food for my daycare center-YIKES!!!! We belong to a co-op for that but it is still expensive!
EDITED TO SAY: I appreciate the advice, I really do, but I can't see where I am blowing the budget each week so the ideas you all are coming up with would work if I wasn't already trying so hard to cut expenses. Perhaps we just live in an area that charges more for food?
