Soldato
See, that's the exact attitude I mentioned in my earlier post. Why should the benefit of trading on the MM sit entirely with the buyer through lower price? The perceived benefit of using the MM to avoid scammers isn't exclusive to the seller, the buyer is also purchasing from someone that's part of the community and therefore benefiting from lower risk.
Pay a fair price, and everyone wins. You don't overpay, the seller gets a fair price and you're getting lower risk versus eBay.
I've lost count of the times I've seen posters offering derogatory offers, someone comes in with either asking or close to asking price and the person who made the derogatory offer then asks to be second in line. If you wanted the item and are willing to pay the higher price, just offer it in the first instance.
Most of my for sale posts on the MM state that I'm not open to offers because I know what I can get for the items via eBay (filter by completed sales of said item). I'll usually price a tad lower on here so there's still value to be had. If I get no bites, I'll put it on eBay and sell for higher.
I agree some of the offers are just complete pee takes. But I feel the general consensus is that people are happy to knock a few quid off for an easy sale. Also you're avoiding eBay fees too which can easily offset the higher sale price on there.
