$32: Amount paid by President Obama at Bunch of Grapes bookstore in Martha’s Vineyard. The president was seen shopping with his daughters, Sasha and Malia, while on vacation in Massachusetts. He was seen holding the books “Brave New World” and “The Bayou Trilogy” among others. The president paid with a credit card (he told the cashier he only uses it a few times a year) and chatted a bit with patrons.
