Target offers the Dickies Men's Regular Straight Fit 5-Pocket Jean in Indigo Blue Washed for $16.99. Better yet, buy two pairs for $25.48 plus $6.99 for shipping. That's the lowest total price we could find in this quantity by $14. They're available in waist sizes 28 to 42 and inseams 29 to 34, although not in all waist/inseam combinations.
Need big & tall sizes? They're available in waist sizes 44 to 56 and inseams of 36 for $3 more.
