Due to "discovering" the CVS deals a few months ago, I have a pretty good toiletry, cleaning supply, etc. stash. Most of it I got free or pretty close to it. I have a little shelf right outside of the bathroom that I put most of it on and also a cabinet above the washer/dryer that I put some of the extra cleaning supplies. Here's what I can think of off hand:
Toothpaste (2 years? seriously, I told my husband I wont buy anymore except to give away. But hard to pass up when free!)
Toothbrushes (a year?)
Shampoo/Condi. (only about 4 sets, still working on it)
Soap (a year?)
Razors (6 months - a year?)
Shaving Gel (6 months?)
Toilet Paper (3-4 months? again lack of space!)
Deoderant (6 months?)
Feminine Products (a couple months maybe, not sure)
Meds (about a year of general aspirin, tylenol generic CVS meds, excedrin, tums, rolaids)
Cleaner (a years worth? I buy concentrated)
Dish Soap (a years worth?)
Detergent (6 months?)
Air Freshner (6 months?)
Baby Supplies (I have a good bit of baby powder, oil, lotion, body wash, etc. due to the baby showers I had. I use this stuff sparingly, so I have a good bit left over even though my baby is 16 months now)
----------------------------------------
For food, I am limited on space. But I have a pretty good supply on hand considering my space restrictions. Here are just the main things that I can think of right now:
Flour, Sugar, Rice & Pasta (in big containers, about a gallon or so in size)
Instant Potatoes (10 boxes?)
Shells & Cheese (3-5 boxes?)
Grits (3 boxes?)
Granola Bars (a couple months worth)
Cereal (7 boxes)
Bisquick (2 big boxes?)
Tea Bags & Coffee (2-3 months?)
Jello (6 months- year?)
Canned goods (as many as I can fit in my small pantry; I buy them when on sale but I stick to the better brands)
Condiments (2 months?)
Freezer meals (I cook large batches and put in our deep freezer) and Fish (what my husband catches)
There are many things that I would stock up on if I had the space. But we live in a mobile home, so it isn't easy. We will look for a house in a couple years and when we do, my requirement is that it have a utility room that I can use for storage!
*** Most people, it seems, who stock up shoot for about a year supply of non-perishables (especially household and toiletry items).
I think it all depends on your available space, your organizational skills (keeping things rotating so they don't expire), and your family's average usage. If we use it and it's on sale (or free at CVS), then I pretty much buy as much as I think we'll use as long as the expiration date is good (meaning, it wont expire before we're able to use it). I really believe in stocking up when things are on sale. It's good for the budget over all and I like the idea of having a stash if something major happens.
God bless,
