Gumtree Scammers

Hey everyone, I'm sure that most people are well aware of scams online on websites such as gumtree etc. but for those who are new to online selling such as myself, I'd like to warn ye that it seems to be more common than people think. I put an advert up on gumtree just lastnight and woke up to five replies, none of them were genuine. They all pretty much had the same ring to them; claiming to pay for the courier to collect the item, looking for my PayPal account to pay on more than I was willing to sell the item for and looking for my home address an funnily enough they all used the word 'kindly' excessively. Anyway, just putting a word of warning out there for new sellers as I am aware of people who got stung out of money because of scammers before.
