They had these at Hy-Vee for 2.99, with a tearpad of 2/1 sitting in front of the display. I didn't think .99 was too bad of a price. They come with three of the bags that you have to use with them. I actually think when my bags are gone I am going to attempt to use them with a regular ziploc bag. I'm just going to shut the bag all except for a little corner , use the vacuum thingy and suck the air out. This should save my lungs

. I've been doing this for years , sucking the air out with a straw.HTH someone
