Our school is raising money for Relay For Life, and we want to put change jars/ piggy banks in each classroom so kids/ parents can send in change. Does anyone know a place to get inexpensive plastic containers for this? I thought about 2-liter bottles, but I'm not sure all the coin types fit inside. My DD has a clear plastic piggy bank, but it was a gift a few years ago and I don't know where it was from.

Thank you for your help!
