I bought a box at a thrift store and used them to move my stash. I would not consider them for long term storage (I didn't even bother sucking the air out) but they were big and worked for what I needed. I wouldn't pay real money for them, I paid $3 for a box of 9 that had 1 bag taken out. It was way cheaper than totes or moving boxes so it worked for what I needed. The pulls on the top of the bags kept falling off and my daughter tore a hole in one just moving it.
