Walmart offers the Hanes Women's Knit Essential Ribbed Sleep Tank 2-Pack in several colors (Black/White pictured) for $3.50. Opt for in-store pickup to dodge the $5.99 shipping charge. That's $5 off and the lowest price we could find. They're available in select sizes from S to L.
Will your package get to you in two days if you have Amazon Prime? Well, it depends.
