Amazon offers the Chex Gluten Free Oatmeal 3-Variety 2-Pack for $5.96. Clip the 20% off coupon under the item's price and it falls to $4.77 during checkout. Plus, Prime members grab free shipping. (Non-members can get free shipping with orders of $35 or more; otherwise, shipping adds $6.08.) That's $1 under what you could expect to pay at a local Walmart.
