Found a good deal on the Blender Bottle

At iHerb.com , if you are a first time customer, you can enter FAN129 and get $5 off your order - no matter how little you order! So, I ordered 1 Blender Bottle for 8.99 (little more pricey to begin with), then shipping was $2.00, minus the $5 discount. Total price = $5.99

That is a great deal ;o) I dont use them anymore but when I did they were almost 10 dollars each. Yikes! lol

What is a blender bottle? Is it something I should get prior to surgery? I have a nice food precessor.
