This deal has ended.
Update 10/5: this is now $39.98! Normally $99.50, Jos. A. Bank has their Men's Cable Crewneck Sweater on sale for only $19.99. Most sizes across four colors are currently available but don't expect that to last. Also, free shipping (and it's 2-day) usually requires a steep $175 order but it is free through Sunday 10/5. This is Australian lambswool.
