we got our ears, base, patches etc in october when there. we also went in april this year and it was available in the store connected to design-a -tee at dtd. it was also in le chapeau? on mainstreet in mk. they can get pricey as they price each single ear, badge, etc. i was astounded that for three for me and the kids was close to 80$. we also had our names put on them too.
however i did not see anything indicative of different countries. they had holographic ears with mickey parts, fireworks, pink princess ones, in october ones with skulls or jack skellington, cant remember now. hth!
