To Expand on the Above: We'll take apples as an example and work in reverse.
Recent LDS price was $62.45 for a case of 6 lbs dehydrated apples, or $10.41/lb. An average apple has 85% water, so crisp dehydrated is 18% the weight of fresh (100 - (85 - 3), which makes $10.41 a pound for crisp dehydrated equivalent to $1.87 per pound of fresh peeled, cored, and trimmed of any defects (10.41*.18). That's your comparison price for frozen apple slices or canned drained apples.
But if you buy a bag of fresh apples, none of that preparing has been done. The average loss after prep for apples is 7% for skin, 8% for cores and stems, and 7% for defects. Assume you bought almost perfect store apples, and make it just 1% for any defects for a total loss of 16% of their weight in prep. So it's $1.87 * 0.84 for a comparison price of $1.57 a pound. If it's a bushel basket with a more average level of imperfections, it would be $1.87 * 0.78 or $1.46/lb. Of course, you haven't spent any time prepping those LDS apples, and you haven't paid for any electric or gas to get them crisp dry or any additional mylar bags and O2 absorbers to preserve them. And on the other hand, depending on how much you order, shipping costs could add up to 50 cents per pound to your dried apples, or $1.96/lb for peeled, cored and trimmed or $1.69 to $1.53/lb equivalent for fresh maximum equivalent costs. Looking at store apple prices here, the LDS apples are a good deal. YMMV depending on where you are, but they are certainly the most economical choice in cans ready to store.
Freeze-dried? Let's look at Northbay's freeze-dried apples in mylar bags with desiccant. You would need to snip a corner off the bag and add an oxygen absorber to those and reseal for long-term storage, although they're good for a year in the pantry as is. If you can wait, you will eventually see them offered at 10% off list as most of their products eventually are in the course of a year or two, but we'll go with current list in their larger bags. Their diced freeze-dried apples in 1.2 pound mylar bags are $3.549/ounce (they do that math for you). Their Fuji apple slices are $3.281/oz in 1 lb bags and their Granny Smith apple chunks are $2.603/oz in 1.5 lb bags, but we'll go with the dices for now. So the equivalent of the 6 lbs of LDS dehydrated apples would be 5 bags exactly of Northbay's diced freeze-dried apples at a cost of $56.78/pound and $283.92 for 6 pounds (or $52.50/pound and $314.98 for 6 pounds of Fujis or $41.65/pound and $249.88 for 6 pounds of Granny Smiths). For fresh apples, the equivalent would be $8.59 to $7.97 per pound. (And now you know why I use dehydrated where dehydrated works as well as freeze-dried. Don't make your emergency food applesauce from freeze-dried apples.

)
What about freeze-dried apples from Thrive Life? They only show Fuji apple slices, 8.46 oz per #10 can and $207.99/case of 6 cans with a total of 3.17 pounds per case if you sign up for monthly deliveries, or $244.69 if you don't. That's $4.10 per ounce to $4.82 per ounce depending on how you buy (plus additional shipping costs you need to add to the $4.82 price because shipping is only free on orders with monthly delivery service, but we'll skip that for now), and that $4.10 is with the current 15% off sale added to the monthly delivery price discount. That comes to 27% to 47% more than Northbay's Fuji slices (and 39% to 63% more than Northbay when their Fuji's are on their own 10% off sale list for the month). And any order over $99 comes with free delivery from Northbay.
Some of that price difference you can ascribe to cans versus mylar bags, but most of it is due to Thrive Life's multilevel marketing business model.
For instance, let's look at Honeyville freeze dried apples in cans, neither the best nor the worst pricewise among the competition, but easy to calculate because they, like the LDS, have a fixed shipping cost. They only offer Granny Smith chunks at the moment (everybody's inventory is a bit spotty these days). They sell a case of 6 cans containing 8 ounces per can, 3 pounds total (Honeyville's cans are always a little underfilled to make their per can prices look better) for $121.45 with $8.99 fixed shipping per order, so $2.72 per ounce if you order only one case. So that's $2.60 per ounce from Northbay for Granny Smith's in mylar without an oxygen absorber and $2.72 per ounce from Honeyville for the same freeze-dried Granny Smith apple chunks in cans with an oxygen absorber. That pretty much reflects just the difference in packaging costs. Therefore, the difference between Northbay's $3.28 per ounce for Fuji apples plus 12 cents for cans instead of mylar bags, $3.40 per ounce, and Thrive Life's $4.10 per ounce for Fuji apples represents a 21% markup to support Thrive's multilevel marketing sales structure. .
And that is how you comparison shop storage foods. Once you are looking at all the adjusted costs per ounce for the various products from various suppliers, you can then weigh up comparative tastiness, suitability for various uses, convenience, comparative shelf lives, etc. and make your own well-informed buying choices for your pantry. While you're at it, you can also figure out what you will save versus cost of equipment and time and effort you will expend to do your own canning, dehydrating, or freeze-drying for mid-term or long-term storage. Different people will have different opinions on whether doing any or all of those themselves is or isn't worth it, but at least if you do the math, yours will be a more informed opinion than otherwise.
