Be sure to allow an absolute minimum of one hour for this store. Its treasures are sunken deep within the piles and piles of literature, media, and miscellaneous items that you may not need but will purchase because they are so freaking cheap. You may at some point end up on a stool somewhere with your morning coffee paging through a Swedish phrase book and finally look up to see the sun setting.
You can plop down in any corner of the store and page through an unlimited number of random books you'd never think you'd find interesting or that you maybe thought would be a lot cooler than they turn out to be and so will luckily never buy. In many cases I find things that I may not read, but damn $2 sounded like a good idea when I was in the Half Price time-warp-induced stupor. Did I really think I'd read 100 Questions You Should Be Asking About Your Personal Finances? Well, another man's garbage is...another woman's coaster. Still a good deal!
The DVD collection is awesome as well and usually worth the patience of scanning through each shelf. $3 copy of Big Trouble in Little China. Enough said.
You probably won't get much compensation when you try to sell books back here, but you'd be getting rid of them anyway so you might as well reap the 50 cents and put it toward your next purchase. Wonderful place to kill an entire afternoon.
