If you read the small print on those coupons, there is a link to a list of manufacturers that are excluded.  Line 6, Taylor, Martin, and many other big names are always excluded.  Then they invite you to call for pricing, but I've never tried it.

I bought my JTV 69 and HD500 on-line from AMS (American Music Supply) as discounted blemished items.  They have a satisfaction guaranty but I was totally happy with the purchases.  They had very light "use" marks but that's it and they came packaged like new.  I think the JTV was reduced $300 and the HD500 $100.  That was several months ago but they may still have them occasionally.

I saw this today too.  Really surprised me to see a JTV on there.  At first, they were offering the Cherry, but later in the day it changed to Black.  But I really like "Hello Music."  It's fun to get those emails every day to see what they are offering next.  You can get some really good deals.  A couple of weeks ago, I picked up a new L6 HD500 for $345 due to their low price plus a $30 "first time buyer" discount.
