Jockey Store via eBay offers the Jockey Men's Stretch Long Underwear Waffle Crew Top in Helios Indigo or Pitch Green (not pictured) for $4.99 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's the best deal now by $6.) It's available in sizes S to XL, although not in all size/color combinations.
Note that although it's pictured in White, it's only available in the colors noted above.
