Walmart offers the Mainstays Value 10-Piece Towel Set in Yellow for $12.13.(White and Office Blue are available for a couple bucks more.) Choose in-store pickup to avoid the $5.99 shipping fee. That's $5 off and the lowest price we could find, although we saw it for $2 less in our mention last September. It includes four bath towels, two hand towels, and four wash cloths.
With these companies, it might be easier than you think to negotiate your monthly bill down.
