Walmart offers this George Boys' Short Sleeve Polo Shirt 4-Pack
in a choice of 11 colors (you can mix and match them) for $20
with free shipping
. That's $10 off list, tied with our mention from two weeks ago (which had a slightly larger collection of colors), and a very low price for four boys' polo shirts. Sales tax is added where applicable. It's available in sizes XS to XXL, although not all size/color combinations are in stock.
