I have a suggestion; it won't help you now however. You may want to look into
Angel Food Ministries. You get an amazing amount of food for $25/box.
From their website: "Angel Food's groceries are sold in a quantity that can fit into a medium-sized box at $25 per unit. Each month's menu is different than the previous month and consists of both fresh and frozen items with an average retail value of approximately $50. Comparison shopping has been done across the country in various communities using a wide range of retail grocery stores and has resulted in the same food items costing from between $42 and $78.
Generally, one unit of food assists in feeding a family of four for about one week or a single senior citizen for almost a month."
My family did it back in August, we got 2 regular boxes & 2 of the specials. They lasted us around 3 weeks, which saved us alot on our grocery bill for that month. We wanted to continue it because it would really help out but an emergency came up & the cash we had set aside for it had to be spent on something else that month. We haven't been able to get back on schedule since then. I intend to start this back up in January though.
