I just bought a cheap acoustic bass on Amazon. I noticed on the page it said "Speak with an Amazon Harmony assistant for discount codes..." I clicked on the link, entered my cell phone, got a call, waited a minute, went through two people and got a 15% discount! I'm not sure if it's on all pages, but if you come across one, it's worth your time to have them call you. I'm attaching a photo so you can see what it looks like. See the phone icon in the middle of the screenshot. My total before tax went down to $325. I have no idea what a harmony associate is, but...Deal!
