Where are these manufactured?

Due to manufacturing regulations in China, it is not possible to know with 100% certainty that the materials are as advertised. There have been too many recalls from China and it makes me hesitate to purchase these, or anything from China that will be used for food. Because these are used for food storage, (unlike something like an electronic) the food is in contact with the material for a long time which increases risk of exposure to any unknown additives in the material. The fact the "FDA & USDA" lets so much foul stuff pass inspection, is probably why it does make a big difference for us to research in order to make better, informed-decisions. The FDA is the same group that takes what's healing in nature, adds chemicals to it in order to patent it for profits, people end up sick or dead, they're caught lying, revise what they said. Rinse and repeat. USDA has also been caught lying by mislabeling things as safe which weren't. As far as the product meeting "US import policies" as a food container, or making it to the US market, that doesn't change serious legitimate concerns involving the recent tampering with our central nervous system and autoimmune system. Research the "biowarfare, biochemical" weapons program in China still in effect. It's "supposed to be" covert (an important detail). Please do clean and wash everything. I would much rather be made to feel uncomfortable by truth, than be, made to feel comfortable by lies. I love my neighbor as myself.

how many bags for this price?

My first response was removed. (keep this in mind when reading the reviews) so I'll answer very succinctly. Yes, the prices are for one bag, unless you get the 7-pack of mixed sizes which, as of today, is about $95. In my opinion glass is far less expensive, safer, and longer lasting. (16 or 32 oz Ball jars cost less than $1/each if you shop them, 1/2 gallon is maybe $2.) There are good deals on Amazon for glass container sets too. The German/France LFGB method of testing is more comprehensive and strict than FDA. When I pay a premium for my silicone I accept nothing less than LFGB food grade, and the premium is usually only a few dollars more, eg, LFGB silicone ice cube trays are about $5 more for a set of 2 ($17 vs $12). This might be a reasonable price for a set of two of these bags. Search for the difference between FDA and LFGB food grade at Just Smart Kitchenware (& checkout the pinch test while you're there.) In time these will get knocked off and the prices for silicone bags will likely come down. A lot. Just as they did for silicone stretch lids and cookware. Competition will probably eventually emerge with LFGB food grade silicone bags as an option as well, and at competitive prices. If this answer gets removed I'm going to the mat, and I'll likely turn it into a review. ;)

How much can a bag store? I'm interested in volume so I can freeze soups (stacked flat in freezer). Is this product appropriate for that?

The snack size stasher holds 9.9 fluid ounces, the sandwich size holds 15 fluid ounces, and our half-gallon stasher holds 64.2 fluid ounces. Stasher is great for freezing soups, however we recommend that you not stack anything on top of a full bag until the contents are frozen.

Has anyone tried this for sous vide cooking? How did it work out?

I purchased a 7" and a 10" for Sous Vide. I agree with the other comment that it is difficult to get all of the air out with these. With ziplock bags, the bag molds itself to the food as you submerge it under the water. The Sasher bags are too thick for that. So the only way I see them working is if you put something metal in the bag to weigh it down. Don't plan on trying to use it with Sous Vide again.
