Walmart offers the Hyper Tough 38-Piece Stubby Tool for $13.02. Choose in-store pickup to dodge the $5.99 shipping fee. It's at least $2 cheaper than what third-party sellers charge via eBay. It includes an adjustable wrench, ratchet screwdriver, 20 1" bits, and more.
These no-name products are at least as good as the branded competitors — and nearly always cheaper.
