Levi's takes 20% off orders of $100 or more or 30% off orders of $150 or more via coupon code "SUMMER". Even better, orders over $100 (before coupon) receive free shipping. That's tied with our April mention and one of the largest percent-off discounts we've seen from Levi's so far this year. (We saw 40% off sitewide in May.) Sales tax is added where applicable, and some conditions may apply. Deal ends July 5.
A best bet is to buy three pairs of Levi's Men's 511 Skinny Commuter Jeans in Road Work (pictured) or Red Ochre for $161.70 before the above coupon, $113.19 after it. With free shipping, that's $37.73 per pair and the lowest total per-pair price we could find by $40. They're available in waist sizes from 28 to 36 and lengths 30 to 32, although not in all size/color combinations.
