Dockers offers a selection of men's pants for $29.99. Add four pairs to your cart for $119.96, then apply coupon code "BUNDLEUP" to knock it to $59.98. With free shipping, that's $15/pair and $30 under the lowest total price we could find for this quantity with such a wide selection elsewhere. Deal ends December 4.
Of note, Amazon offers Prime members a few pairs for as low as $13, but only in very limited sizes and colors.
