5StarDeal via eBay offers the Remedy Memory Foam Compact Travel Size Pillow

. That's the lowest total price we could find, outside of the price below, by $4. (We briefly saw two full-size memory foam pillows for just $2 more early this morning.) The pillow measures 12x9" and features a zippered cover that can be removed for washing.
A close price: Kmart has it for $11.99 plus $6.50 for shipping. Sales tax is added where applicable.
