Walmart offers the Wrangler Men's 5-Star Relaxed Fit Jeans with Flex in several colors (Dark Denim pictured) for $15.10. Opt for in-store pickup, where available, to avoid the $5.99 shipping charge. That's the best price we could find by $11. They're available in select sizes from 30x30 to 42x32.
With these companies, it might be easier than you think to negotiate your monthly bill down.
