It's a warehouse, so stuff isn't priced, but since we don't have an LSS here, I'm like a kid in a candy store at MouseMemories - a kid with an income! WOO HOO! I especially like the Zahara or Zatara (I forget which) papers (designer theme park papers), and the textured cardstock that comes in a 'suite' of colors that coordinate, which of course is not theme park specific but I go through a ton of it! They also have tons of college, sports and faith based stuff.
One other thing about it being a warehouse - it's not set up with enticing displays, but rather for efficient order pulling. I buy less stuff on impulse and more stuff that I actually had on my list, if that makes sense.
I rented a car for a day and grouped all my off property shopping - MouseMemories, a couple more scrap stores, the LBV shops. It worked out to less than $40 for 24 hours, and I would think taxi fare would be about 40 from property, since it's about as far to MouseMemories as to the airport.
