I have been saving up my change for 2 summers working at a restaurant.
I try to get rid of a lot of my change while at work because honestly I prefer the bills (especially the red and brown ones), but I do accumulate quite a bit of change as well. I bought a change jar and have been filling it up with "snowflakes" as Jolie says and calculates monthly.
After buying two bags of coin rollers and trading a few with my parents I was able to roll $1026 in change! I had planned on using that jar money toward a vacation one day and I think that is exactly where it will go! Already starting to add to the jar again!
