Yes, agree. Pink a la mode, Boxlunch, Artland, Kraken, DisneyPinsBlog, HotTopic Figpins all sell legit pins (these are just a few random sources). Many have a secondary relationship (do not understand it any further than calling it a relationship) in order to use a Disney License to create most of their pins (Uncas, Loungefly, Monogram, Salesone, Bioworld, etc).
I have seen Figpins and Funko POP! (owned by Loungefly) branded pins for sales in the parks, so there is a bit of crossover from licensed pins into Disney properties.
