Reading this thread reminds me of what a ridiculous obsession I have with Disney Parks merchandise.
I am a shopaholic (bad bad me), and much of my anticipation before each Disney trip is figuring out what items I will buy when I am there. DH and I are hopeless toy collectors, and we usually spend quite a bit on toys and other souvenirs while we are there: he at
Lego Store and Tatooine Traders and I at Once Upon a Toy, World of Disney and Days of Christmas.
Probably the most expensive set of items we have acquired is the original Monorail set. I can't recall if we purchased the set in 2000 or 2002. The total cost for everything (with shipping), including the Monorail Yellow, Monorail Black, TTC, Contemporary, Polynesian, Grand Floridian, Spaceship Earth (original), Castle, Dumbo, Teacups, Haunted Mansion (WDW), and diecast ride vehicles, was just under $500. I believe we purchased the Wilderness Lodge Lincoln Logs (see my avatar) on the same trip.
Here is a picture of our original setup:
Can you tell we have no children and extra bedrooms?
We have since acquired most of the other pieces, on our subsequent trips and on ebay, including the Resort Signs, Train and Main Street Train Station, Spaceship Earth (updated), Sorcerer's Hat, Tree of Life, Haunted Mansion (DL), California Screamin' (purple car), Orange Stinger, Triton's Carousel, Sunwheel, and Golden Zephyr. Space Mountain, the Golden Gate Bridge, and other items are still on my ebay wish list. I won't even quote prices for the whole set, as I don't really know the total and don't want to know.
Here is a thread with pictures from someone who has basically the same pieces we do:

The Potato Head parts have probably been the second most expensive set of items. I recall on our trip to
Disneyland in 2005, we spent nearly $120 for 5 boxes of parts, ones that had been released since we acquired the original parts in 2002. We have virtually all of the Potato Head parts, but as with the Monorail set, I have no idea what the total cost has been. My favorite is the YOMD hat. Here is a complete list of the parts:
