I have been asked to provide a postage cost to Singapore, but am a bit hmm at the whole thing

[Saltire]

I listed a ralph Lauren tote bag, it was a free gift. it's not what I would class as a "desinger" item or anything.
Anyway, someone in Singapore has contacted me, and aske dme for postage costs to their country and an offer to BIN(which I'm not going to accept), but I keep thinking "surely they could get it cheaper/ a copy cheaper over there" and wodner if they are gong to claim it's fake and send it back, but send back a fake instead.

Could you just say that you don't post abroad?

I did, but they keep saying that they are prepared to pay and don't care how much it is!

Just keep replying to them stating that you don't ship abroad. Have they made a bid? You could always block them.

It's probably too late now but even though I state that I do not post out of the UK I had someone bid on an item from Germany. I contacted her during the auction with an offer to remove th bid but I heard nothing. When she won I contacted her again to say that I don't post abroad but was ignored again. In the end I send her an invoice with postage at £50! She replied then and said it was too much.... I pointed out that I'd made numerous attempts to contact her and that my listing clearly stated that I wouldn't post abroad - she got the message in the end and apologised for thinking that if she won I'd simply give in and post it at the UK cost.
