"Space Bags" ---- Space Savers or Money Wasters?

Yes they do, just make sure everything going in the bags is clean and you have a good vacuum to suck out the air. Another tip: Through in a few socks filled with baking soda so that things smell fresh (But not like chemicals or perfume) when you take them out. If you put a dryer sheet in and store the bags for a few months, things will be heavily scented afterward because when used properly, these bags are airtight. The males or anyone else in your family probably won't want to smell like "morning freshness next fall.
