Is this too far from you?:
Super Target
175 W Center St
Orem, UT 84057
They have affordable bookshelves...
I've been using the cheap bookshelves that Walmart sells so far, and ouside of the Tower Bridge and the SSD, everything fits. I was just thinking going forward if there was anything else that would be useful to use for display, outside of buying longer/Deeper bookshelves.
Edit: http://www.walmart.com/ip/Ameriwood-3-Shelf-and-5-Shelf-Bookcases-Mix-and-Match/22282370 These are the types I have so far, and Ill probably end up picking up another tall one to fit the UCS Xwing and Palace Cinema I picked up on vacation last week.
