Walmart offers the Lifetime 44" Streamline Impact Basketball System for $63.99 with free shipping. That's a buck under our mention from a month ago and the best deal we've seen. (It's the lowest price now by $26.) It features a 44" backboard, telescoping height adjustment from 7.5 to 10 feet, 12-gallon portable base, rim, and nylon net.
June brings some big deals and sales, but you're better off postponing certain purchases.
