Today at Galaxy's Edge they started selling the Darksaber from the Mandalorian inside Dok-Ondar’s. Here's a picture from Disneyland News Today:
Doesn't seem to be really worth the price, but as far as I'm aware this is the first Mandalorian themed merchandise to be exclusive to GE, with Disney previously having merch carts under the bridge (technically in Frontierland) selling Mando knick knacks so not to break canon. Makes me wonder if we'll see more themed experiences for the Mandalorian come very soon to Galaxy's Edge.
