I've read his reply and found nothing rude in it.
I don't understand why you find the replies are rude?


Replies are short and straight to the point. With little elaboration because I'm sure the seller got many other messages to reply to other buyers as well.


And seller properly ask you to go ahead and buy from other sellers if you think can get cheaper price elsewhere.
So if you think the price is expensive then just don't buy.

I for once would say you are the one pouring down accuses after accuses without backing up with facts / proofs / or anything at all?
You are the one saying this and saying that but where is the proof?


From the seller reply (the printscreen in the first post), and also all the replies here, I can't see any rudeness in it.
