Also went to Whole Foods--which seems to be unchanged, although with my usual grocers getting rid of luxury goods, WF stock might be an item. I made a little bit following this years run up of WF. (Although it's a more practical "stock" I'm talking about.)
For some reason, Walgreen’s has been running deep specials on 2 or 3 mainline cereal selections each week...I have been able to save several $ by watching their shelves and stocking up, but only for the short run...limited storage space...:(
For milk, look in the Mexican food section for Nestle brand powdered whole milk called NEDO. It’s an excellent product I keep on hand because we live so far from town.
No comparison to MOO MILK available in 5 gal buckets which is an artificial milk substitute which is made from soy and tastes terrrible.
milk: any store with a large Hispanic section has dried Nido whole milk. It has a 10 year shelf life. Drawback: it only is available in my area in 10# cans. When it is opened, I will parcel it out and vacuum pack smaller portions.
I also buy gallons of whole milk when they are on sale and repackage them in 8 oz portions and freeze them in double bags. There are only two of us and we don’t drink a lot of milk, so it lasts a long time.
I also buy evaporated whole milk and, again at the Hispanic stores, Nestle’s Media Crema, which is close to heavy cream. It can be diluted to taste. Both have 2-3 year posted shelf life.
One thing that I don’t see mentioned is BUG SPRAY.
Powdered milk
You can buy powdered milk in advance. It also comes freeze dried in nitrogen packed #10 cans and seems to store well. I just opened some I purchased a couple of years ago and it was good.
