What Percentage Off Would You Expect to Discount For Open Box Amp with Blemish

The amp is also a discontinued model which I believe should be further discounted.  So how much off  on a $3200 amp is the question? I called the dealer with a few questions. I asked if the amp would be on sale for Memorial Day since it’s a discontinued model. The girl said they didn’t do many sales on this brand (I know they do) Anyway,  she looked and found an open box in warehouse. She knocked 12% off MSRP. Does that sound right? Or should there be more discount due to blemish?  I think the later. I’ve always thought 10-12% off to be the norm discount on prime products.I know this isn't set in stone. But what is "normal" ? Whats your thought? Thanks for your input
did they send you a photo of the 'blemish'? easy to live with? then you are lucky. you have heard this, determined it is very desirable? return option?

I always am aware that anything I buy will end up with a blemish or two, primarily my doing, so I am a big fan of open box, as long as the full manufacturer's warranty applies. not a blemish I have to see every time I use it, something out of sight when in use,

or, something on the passenger side of the car!!! Next accident I will have that dealt with.

You know they regularly have sales, so that would be 10-15%, then you have open box discount, so I agree, don't ask, make them an offer, figure out -25%, offer them that in writing, i.e. email, with confirmation of warranty and return in that email. that allows them to forward the email to whomever makes the final decision without anything lost in translation.

clarify: credit card? pick your credit card with best protection. option for extended warranty? So, you get a discount, spend it on the extended warranty, sleep easy. 

They come back, 20% off, yay or nay? don't forget, any discount/sale, you save tax also, so that helps your final price/decision.

good luck
OK guys. I was planning on making them an offer. I was juts trying to determine what amount. I was in business most all my life so I I don't begrudge a man his pay.  At this point, I have doubts about the amp...or should I say the dealer. I called on Wed afternoon. Then later that day to see about getting pictures of the damage. I assume its not bad. But we all know what assume stands for.

Anyway my messages for a return call and pictures have not been successful.  I asked for Pictures &  was told it would take a few days. That was early Thursday. I have heard nothing. I thought about emailing  an offer but I'm old and prefer to do business with voice rather than email. 

As for the amp, it is new open box from auth dealer. The amp is a class A S'phile pick so I understand that the discount may not be as much as for others. But it is still open box with blemish  and a recently discontinued model. I have a # in mind so may as well do it

Anyway Thanks Guys
I hope you’ll at least reveal what this is once the matter is settled???
Why a big secrecy about the brand of amp and what kind of "scuff" mark it really is? Is this a Top Secret amp? The brand makes a big difference, you aren’t going to get the same amount off for a FM Acoustics or Goldmund compared to a Marantz, Pioneer, Yamaha or similar.  That is why I ask the name of the amp.
What is the mystery amp and did you buy it??HELLO!!!
