Keurigs are great,and they are all the rage right now. The down side is that the K-Cups are expensive but this is a great way to reuse them. Check this out:
Here is the info:
Peel the top off a used K Cup
Make sure to rinse it out
Fill with 1 scoop but don’t pack it tight or overfill or you are headed for problems (LOL)
Cover with aluminum foil and make sure you pull it taut around the rim.
You can reuse this several time, Frugal for certain!
