Vacuum bag here too.
If you dont have the foodsaver setup, use a freezer Ziplock bad. Fill your sink with cold water. Zip the bag about 3/4 then submerge the bag into the water keeping the open corner of the bag out of the water.
The pressure of the water against the bag will get most of the air out. Then zip it up, pull it out of the water and throw it in the freezer.
I hope that I made sense...
