Amazon has a bonus coupon available for a 20-ounce bottle of Johnson's baby oil.
It's typically priced at $9.05, but it's on sale for $5.90. Clip the coupon for 15% off, then check out with Subscribe & Save. If you're subscribed to five items or more, you'll get the maximum 15% discount and pay as little as $4.12.
Here's how Amazon Subscribe & Save works and how to cancel an Amazon subscription if you change your mind about a product.
