Once a year, bibliophiles and bookworms across the Valley congregate for a long weekend of standing in lines and rifling through stacks and stacks of books. Like the pilgrims heading to Canterbury, devoted readers converge on the Arizona State Fairgrounds, to score some sweet finds at the annual Volunteer Nonprofit Service Association book sale. VNSA virgins will be surprised by the shockingly long lines that snake around the parking lot. Folks line up way before sunrise for a chance to get a first crack at a huge warehouse full of books. The VNSA collects book donations year-round, amassing a huge collection of works — everything from best-sellers to rare, one-of-a-kind volumes. Most of these books are priced to move, so a frugal book fiend can walk away with a shopping cart jam-packed with goodies. And if you can stand to wait until Sunday, the already low prices will be slashed in half.The 2019 sale is scheduled for February 9 and 10. Mark your calendars, stash some cash, and get ready to line up at the crack of dawn.
