Should there be concern?


Recently I ran across an item of interest to me here on audiogon. As I read the entire ad I found it strange that the condition of item said new but the limited informative text said it was used until recently. I send the seller a private text regarding this and the limited information suggesting he should change and add more information.  I received a nasty reply and was promptly blocked by the seller. Would this raise red flags to anyone else or am I just being too sensitive?

Update, looked at ad I was interested in again. Seller did change condition rating from new to 7/10 and dropped the price from $450.00 to $390.00. I would still refrain from doing business with the individual.
Description of item has not changed from original and is very limited.
^^^ @s1nn3r , the list price alone is enough reason to walk away from that deal!

Less than 10% off the list price for a used piece of audio gear???!!!
Hell, I wouldn't buy brand spanking new with less than a 10% discount, let alone a used "for less than 1 hour" item.
