OK...an option I didn't think of was using mason jars with the food saver. I pause at the price of the bags they are not reusable. How well do the mason jars keep dry goods compared to the bags?
Thanks

Properly canned mason jars will keep food edible for at least as long as mylar and bucket, and likely as long as aluminum canning.
However, from a price perspective, one 5 gallon mylar bag usually costs about $2.00-$3.00. 20 1-quart mason jars is going to run you around $1.00-$1.50 each or a little more, for a total of $20.00-$30.00. I agree if you're using mason jars annually, you'll eventually save money, but if these are for long-term storage of 5-10 years or more, there's not much that is more economical than mylar and bucket. Even with a 5-gallon bucket, your total cost for storing 5 gallons is around $9.00, and the buckets can be re-used.
1-gallon mylar bags run around $.50-$.75 each, or around the same $9.00-10.00 (though you'll fit fewer 1-gallon bags in a bucket than just 1 5-gallon bag because of their generally poor shape)
Larger half-gallon mason jars are going to run around $2 each or so for about the same overall prices.
A final note; you need to be much more careful storing mason jars as well: they are breakable, they are much more light-sensitive, they are heavier, and they are more difficult to stack.
Now, don't get me wrong, I actually love mason jars. My grandmother used to can just about everything in them. They are usually a good size for just a few servings of something as opposed to a whole bunch of servings in a bucket. However, if one is talking about the best and cheapest way to store long term, I think it would go something like: #10 cans, 5-gallon mylar and bucket, mason jars. For storing short term (6-months - 2 years), I'd turn it around and go: mason jars, 1 gallon mylar and bucket, #10 cans. (because a #10 can has a similar cost or more than a mason jar, though is unlikely to be reused)
