For decades, there was a store just outside the gated entry to The Haunted Mansion at Walt Disney World in Lake Buena Vista, Florida. It was called The Yankee Trader, and the store would have some HM merchandise in it, but the store was clearly geared towards other merchandise. Now, the store has been completely rehabbed and renamed Memento Mori and the store is ALL HM merchandise.
The link has pictures of the store facade (check out the big "eye" right above the store sign) and much of the HM merchandise. Live Links can take the reader to where the merchandise can be purchased online. Sample of a HM Bowl that can be purchased online at the Disney Store. The Disney Store Online's Available HM Merchandise. I counted 57 items, not counting all the dinner plate/bowl/saucer options.
Cannot wait to go inside during my next trip to WDW!
