When my three went through the "Sassy Stage" I really truly had "fun" with them.
I put cut a "coin slot" in the lid of a mason jar and put a label on the jar that said -- "Is It Worth the Price?"
For each "offense" there was a price attached. The kids were required to drop the coins in the jar and then on Sunday, they emptied the jar in the collection plate.
We "gave" a lot extra for a long time.
We were mean parents and my kids were so deprived.... we had ONLY one telephone for a family of five -- and for years their dad tied up the phone most of the with his business. They did not have a TV in their rooms - in fact for many years we didn't even have a TV, cell phone????? you've got to be kidding

.
We did have a couple of computers that were available to them, but they were all in "public" areas of the house and they scheduled their computer time.
