The Body Shop offers four Body Shop Soaps for $10. Plus, bag free shipping via coupon code "STAYWARM". That's only $2.50 per bar, the lowest total price we've seen this year, and a current price low for any four bars by $7. (For further comparison, we saw 50% off in our expired mention from two days ago, but that deal did not include free shipping.) Deal ends November 24.
A best bet is four The Body Shop Vanilla Brulee Soaps (pictured) for $10 with free shipping via the above coupon. That's $14 off list and the lowest total price we could find.
