B2B is different from B2C. With that being said, just checked their B2C site - for example a commodity like women jeans is $25-35 on the low end. The Land's End manufacturing seems to be mostly China, India, Mexico. It is hard to be cheapest than that.
I’ve been involved in purchasing reasonably large quantities of uniforms (because why not also stick facilities and other random stuff under IT so we can exercise our “purchasing acumen”).
Land’s End is mid-range in cost and quality as far as uniforms go. Especially compared with the super-cheap drop-ship-from-Vietnam vendors.
