Sears offers the Craftsman 30-Piece Router Bit Set, model no. CR-26366, for $69.99. Plus, Shop Your Way Rewards members bag around $10.70 in SYWR Points. (Not a member? It's free to join.) With free shipping, and assuming you'll use the credit, that's tied with our mention from last April, a savings of $71, and the lowest total price we've seen. It includes a case with labels showing the profile of each cut and flush trim, straight, chamfered, edge forming, raised panel, rabbeting, and joinery bits with 1/4" shanks.
Of note, Shop Your Way Rewards members may be eligible for additional credits and discounts.
