Macy's offers the Karen Scott Women's Classic Sweatshirt in several colors for $5.93. Opt for in-store pickup to dodge the $9.95 shipping charge. (Or, get free shipping with orders over $100.) That's $9 off and a very low price for a sweatshirt in general. It's available in sizes from XS to XL.
You probably don't need a year's supply of toilet paper to survive an outbreak, but consider stocking up on these items.
