Macy's offers the Weatherproof Vintage Men's Mixed Stitch Crewneck Sweater in several colors (Parchment Heather pictured) for $13.96. Opt for in-store pickup to avoid the $9.95 shipping charge. That's $66 off and the lowest price we could find. It's available in sizes from S to 3XL.
Vinegar is arguably the most versatile product in your house. If you aren't using it for all of these purposes, you're probably wasting money.
