When in WDW for our wedding and honeymoon-- we asked EVERYWHERE and looked everywhere for anything scrooge related. The only things we came out with were a moneyclip, trading pins (not that we purchased, but discontinued pins on cast members lanyards), a $45. Raddko ornament, and a drawing from a disney artist.
we did recently find the snowglobe on disneyshopping.com... i got it for about 40.00 on sale with a collectors pin. Worked out well-- but that was the only scrooge thing out.
We even tried the christmas store (since he is a christmas character as well) and they only had that single ornament.
he seems to be a dying thing... but -doesnt hurt to try!!
