If you missed SSUK's post you can check it here. Or if you don't want to click the link his post is called, "get silver and gold the easy way #469". Or search, "365-day penny (pence) saving challenge", and you will find more info then you could ever want about it.
The way it works, in a nutshell, is to pick a start day and each day for a year save that many pennies. In other words on day one, save one penny, day two, two pennies...on day 364, put in $3.64 (or 364 pennies if you are a maniac). By day 365 (one year) you will have a jar with $668!

So here we go, my jar is ready.
My first penny is in. See you in a year, little guy! :)
The box is checked and we are in business.
Let me know what you would pick up today if you had $667 burning a hole in your pocket.
Then join in the fun and make it a reality in a years time.
