Did you know you can seal any plastic bag without an expensive sealer?
Simply fold a piece of aluminum foil over the edge of the bag that you want to seal. Then run a hot iron over the edge (making sure the aluminum foil is covering BOTH sides where you are running the iron). It will seal the bag, and you can keep packages fresher longer!
Of course, this tip is for you only if you actually own an iron, I know. But it gives some of us an extra excuse to dust the iron off ;)
