yeah, having a change bucket, is a great thing, i havent cashed mine in for around 1 year, and i am pushing 150$
also something i would recommend people look into, is a CD, if you have money in a savings account that you dont plan on using for a little while. get a CD, i have around 4,000$ in CD'S and i stand to make 250$ in interest, by the time i cash them in this fall to pay for college.
the interest rates are way better than a normal savings account, and you can get them in time spans as short as 3 months, depending on your bank.
