Despite a $50 retail price, Dick's Sporting Goods has a dozen of the [[Nike ONE Black Golf Balls for $29.99. These are even $40 at Overstock.com. Shipping adds $4.99 or is free if you spend $75 (buy 3 boxes) of golf items. There is no sales tax (except in CA, GA, IL, KY, MA and PA). The Nike Black feature an oversized core and are designed for golfers with more aggressive swing speed (read: your average, inpatient hacker). Unfortunately, Dick's Sporting Goods coupons are not valid with Nike Golf purchases. The price is the best around, however.
