There is a new $.50/1 Thai Kitchen coupon available (try zip 90210).
The 1.6oz Noodle Soups are priced at .99 at many stores- if your store doubles coupons you should be able to get them free.
The Coconut Milk is usually priced around $1.00 at many stores-so you might find a great deal on that as well.  I found it for $1.42 at Target but I believe Whole Foods and Walmart have it priced a little cheaper.
