I eventually found a parking spot and walked into Half Price Books.
After spending about a half hour there, I found some items at a good deal. With my $5 off coupon in hand I finally walked to the checkout area.
I left with:
2 books at $6/each.
2 books at $5/each.
2 books at $2/each.
(One Max Lucado book, two screen writing books, and three writing books.)
I'm sure I'll be back later to browse and treasure find.
