Here's my copy of ROTW 4th ed. EBay prices are absurd IMO so I'm cutting them in half for the rocketry community. If it doesn't sell I'll go with eBay and ludicrous pricing/fees. Condition is "very good" to "excellent". No writing anywhere, corners are not significantly 'bumped', page edges are clean. $65 plus actual postage in the lower 48. Paypal, check, money order. PM for details.
