Two more favorites - "free" "barter"
"pick- your -own" - OK not one word unless you run it together like a sign in my area
Hmmm..."cook"...that would be instead of eating out.
Or "rent" instead of going to see a movie.
Or how about "walk" instead of driving around the parking lot a few times to get the closest spot to the door.
Leftovers- (make sure you use them)
Simplify- (Get rid of stuff you don't use)
Ebay (or) Craigslist- (Where to sell your stuff)
Seeds- (Instead of plants)
Refinance- (If you can to a lower rate)
Unplug- (If you unplug electronics, it will lower your utilities- sometimes by 1/3!)
Reconnect- (With family, friends and nature to find free entertainment)
Barter (always a good option when possible)
Bike (instead of driving where possible)
