I can't afford an electric sealer.. and if the SHTF.. there may be no electricity.
Me being a big Google and coupon fan.. I found this site.

http://dealspl.us/imageview.php?f=100306Food Saver Jar Sealers- I use both wide mouth and small mouth jars. You can find the small mouth sealer at Bass Pro Shop.. but they do not have the large. I ordered direct from Food Saver.. as that was the only place I could find the wide mouth sealer. Since I was ordering.. I didn't worry about going to Bass Pro.
Cost of both jar sealers- Lg - $9.99 Sm 7.19 = Total $17.18 forgot what shipping was.

Total price for Non-electric sealer and 2 Food Saver Tops- LESS than $25.
PLUS.. I have a free flashlight.

We use our sealer everyday!! Yesterday I made homemade crackers... stored the rest in a wide mouth quart jar. Storing heirloom corn seed tomorrow, after it comes out of the freezer.
