Amazon offers its Prime members the Thai Kitchen Organic Coconut Milk 13.66-oz. 6-Pack for $4.76. Clip the 20% off coupon and add it to your cart via Subscribe & Save to cut the price to $3.57 and bag free shipping. That's a $5 drop since our mention from three weeks ago and the lowest total price we've seen. (It's about $10 less than what you'd pay at a local store.) It's both dairy- and gluten-free.
Note: Be sure to cancel Subscribe & Save after your order ships, or you'll be billed for subsequent shipments.
