Vitacost's $10 FREE for new members offer. Once I started digging through the site I found all kinds of good deals to be had with that credit. And the good thing is that shipping is only $4.99 flat, no matter how big or how heavy your order!
One of the deals I found is Arrowhead Mills Organic Golden Flax Seeds 14 oz packages on sale for only $2.59. You can get four packages for $10.36, less your $10 FREE credit when you create an account, for a total of $.36 plus $4.99 shipping - - FINAL COST $5.35!
Another option for your credit is the 3 Bottles of Mrs. Meyer's Clean Day Liquid Hand Soap for a total price of $5.67 - great deal!
