$15 Money Maker at Walmart.com on Neutrogena Clinical Products

Edited to add:  Looks like these are already sold out online.  You can still purchase them in-store and get a full refund using the mail in rebate, but unfortunately there is no $15 gift card with the in-store products.

Walmart.com is offering a free $15 Walmart eGift card when you buy any Neutrogena Clinical product.  But it gets better than that because these items are part of a try me free rebate.  Shipping is only 97 cents to your own home, so you get the cost of the products back via Mail in Rebate plus you get a $15 eGift Card.  This gift card is only good to use at Walmart.com so I'm sure you will be able to find something.  Important tip, be sure to print the confirmation page immediately after your purchase for a receipt because the email confirmation you receive later reduces the price of the gift card.
