Refill smaller containers instead of buying new ones everytime, we go through soy sauce like it's nothing so I buy the big jug at Costco and continue to refill the small bottle. This jug refills the bottle 4 times, if I take the price I would have paid for 4 10oz bottles and subtract the amount I pay for the 1.2L jug, I end up saving $6.97.
If you use coffee creamer there is always a bunch left at the bottom that won't pour out so I pour hot coffee in the empty container and shake it to get every last bit of the creamer out.
You can freeze ripe bananas if you have some that are going bad. Bananas left in their skins will freeze for 6-7 months or you can peel and freeze them whole in a Ziploc bag, just take them out when you have time to make banana bread or throw them in a food processor and you have instant "banana ice cream".
Bummer, your favorite lipgloss ran out or you know there is more foundation left in the tube but it won't squeeze out. Cut open the tube and there is usually several more applications left, you can do this with sunscreen or toothpaste, to be honest I don't cut my toothpaste tubes open, I don't want to deal with the mess but I know there is usually a ton of toothpaste left in the tube so if you want to, more power to ya!
This is a good one, my neighbor showed me this one and I thought it was genius, she's not quite as crazy as me, but close. If you've got a little bit of mustard left in a jar, pour ingredients right into the container like vinegar and olive oil or whatever you use, shake really well and voila' you've got salad dressing.
Don't throw away honey if it has crystallized, revive it by putting the container into a bowl of warm water or put it in the microwave to heat for a few seconds, be very careful if you use the microwave, the honey can get scalding hot!
Save your butter or margarine wrappers in a ziploc bag in the freezer, there is usually a lot left on the wrapper so use them to grease muffin tins or cake pans. You usually grab a blog glob of butter on you fingers but most of it gets wasted and you have butter in your finger nails all day even though you wash 100 times, if you use the wrappers your hands stay fairly clean and you just toss the wrapper when you're done, no waste!
This has to be one of my favorites! Do you get the money mailer envelope in the mail full of coupons for local businesses? Whatever coupons I don't use I save and use the paper to print more coupons like the ones from Coupons.com. Each sheet is the perfect size to print 1 coupon, the stores don't care as long as it is clearly printed and will scan.
