Amazon has an 8 pack of the Gain Liquid Fabric Softener, Original Fresh, 60
Loads, 51-Ounce Bottles for $31.43 with free shipping. That comes to $3.92
for each bottle. Closest I could find for a single bottle was at Walmart for
$4.18 plus tax and shipping. If you checkout with the Subscribe & Save, it
comes to $26.72. Most recent price on Amazon apparently was $47.63.
