Target via eBay offers the Hanes Men's Premium Activewear T-Shirt
in assorted colors (Deep Red pictured) for $4
with free shipping
. That's tied with our mention from two weeks ago, $3 off list, and the lowest total price we could find. It's available in sizes S to XL, although not in all size/color combinations.
Note: It's available in size XXL for $6.
