OK, I'm putting this in the Disneyland section because I get these at Disneyland, although I'm aware these are multi-park issues

Does anyone else here get the Collector packs? For those who don't know, they are little packages (I usually get them at Engine-EARS) with three little characters in them to collect. I don't hear about them much, so I wondered. Actually I never knew about them myself until my mother bought me some.
