@Daver - This thread exists to generate awareness within the AF-UK community regarding the price attached to certain adverts. On the whole AF-UK tends to have a lot of banter and at times it can have a very dry sense of humour, however, if an advert ends up in this thread usually it is warranted and how you choose to respond is up to you. At the moment your initial response was fairly reasonable, if somewhat final, which is perfectly fine but the follow up is typical of many responses we see from those who are either new to the forum or who take offence at the mere mention of the name here.
A significant number of people who are mentioned in this thread fail to engage with it and that is entirely up to them. The two other types of people who tend to respond typically respond in one of two ways. The first way is to become defensive and, usually, abusive to some degree. The second type will either qualify their asking price (which you're by no means required to do) and/or seek feedback as to why their advert ended up being highlighted.
One thing to bear in mind is that Hitman was not offensive towards you nor did he direct any criticism towards you beyond viewing your advert as "a little on the high side" which is perfectly understandable when you consider the asking price. This isn't to say that the asking price isn't justified, especially taking into consideration the Plano case costing around £140 by itself in the UK, but bear in mind that the general rule for airsoft guns and accessories tends to be 60% - 70% of retail, typically based on cheapest reputable retailer. Availability being the obvious caveat as a further consideration point.
Finally, I'd recommend removing the batteries from the bundle and making them an optional extra. I'd also suggest doing the same for the optic and pouch. You may also want to fill in some details such as the manufacturer and model of the scope along with the manufacturer of the pouch.
