Missed a good deal

Just missed a listing for a PW3 45 Lmm LTE

For $340 AUD (about $200USD)

And it was 5 minutes from my work, messaged the guy and he's just got back from selling it as I messaged 😭

Next cheapest I can find is almost double and in another state 😂

Anyone know of any other sites to use besides gumtree and eBay?
