I just saw this come across my email from The Happy Housewife and thought I'd repost it here. I don't personally use gluten free products, but know a few people who do. I hope someone can benefit from this.
It looks like Amazon.com is having a Gluten Free Sale. Many gluten free products are 30% off and you get free shipping when you use the subscribe and save option.
Remember to check the prices on Amazon.com before you order to make sure you are getting a good deal. I know gluten free mixes can be expensive at the store so this might be a good time to stock up and save with Amazon's Gluten Free Sale.
Thanks goes to The Happy Housewife.
