For Prime members only, Amazon offers the Nongshim Shin Ramyun Noodle 4.2-oz. Soup 20-Pack in Gourmet Spicy for $16. Order via Subscribe & Save to drop that to $15.20 and bag free shipping. That's 76 cents per pack, tied with our mention from last week, and about a buck less than you'd pay in local stores for this quantity.
Note: Be sure to cancel Subscribe & Save once your order ships or you'll be billed for subsequent shipments.
