I think it depends on which state the seller is from. Not all states have service centres for some watch brands. Talking about shipping a watch all the way to the service centre in KL and risk it being lost in the process? I dont think I would do so as a seller.
Yea, that's another thing, even if you're convinced the watch is genuine, there're still other potential problems when you deal over the internet
I mean, the seller can just refuse to ship it to you once you banked in, for example
Maybe get them to deal through Shopee or Lazada or something, although I'm not sure how good Shopee and Lazada are at protecting their buyers when something goes wrong
But of course even if Shopee and Lazada are able to protect the buyer, they're naturally going to take a cut from the sale, and it is unlikely the seller will absorb it, so he'll simply mark up the price of the watch to pass the cost on to you
Then again, if it isn't much, it's still worth it if Shopee or Lazada can offer good buyer protection
