Performance Bicycle offers the Fi'zi:k Ardea Mountain Bike Saddle in Black for $54.99 plus $9.99 for shipping. That's the lowest total price we could find by $31. It features a nylon carbon base, wing flex shell, Microtex cover, and manganese rails.
Performance Bike cuts up to 50% off a selection of men's, women's, and kids' bikes. (Prices are as marked.) That's tied with our mention from January as a rare discount from Performance Bike, as bikes are typically excluded from discounts. Shipping starts at around $10; most items also include an oversized item charge, which starts at around $12.
