Hanes Brands Outlet via eBay offers the Champion Men's Cotton Jersey T-Shirt in six colors (Yellow pictured) for $7.99 with free shipping. That's tied with our mention from a year ago and the lowest total price we could find by a buck (outside of the mention below). It's available in sizes M to XXL, although not in all size/color combinations.

Of note, Amazon has it in select colors (and limited sizes) for a few cents less.
