Investment cooking is a great idea and I use it regularly.
In our family, there are three of us (my mom,
daughter and myself) that whenever we run across a really
great deal on items, we purchase enough for the three of us.
This past weekend, I got a great deal on briskets
at $0.88 lb. I purchased three for $21.00! Now my daughter and
mom will pay me for the cost of theirs. My daughter recently
found whole pork loins for $1.00 lb. and bought three. We each
purchased one from her. I had 5 pork loin roasts after I cut
them and sealed them for the freezer at less than $3 lb. Mom
bought 50 lbs of onions for $8.00 to use in canning. We each
bought 5 lbs from her at a substantial savings.
Since we each shop at different stores, this is a
great way to save. If you have relatives nearby or are on good
terms with your neighbors, it can work the same way.
