If I was to draw any correlation it'd tend to be the dreamer/borderline dreamer posts tend to increase around paydays. I'm assuming that's folks seeing a new shiny they want from their hard earned coin but falling slightly short, dipping into the collection to make up the difference. In the case of that admittedly overpriced CM.041 my initial thoughts were 'I wouldn't pay that, but also find me another in stock' (which is now somewhat moot because TG have had a restock, granted some aren't willing to buy from TG at present). Very much priced to catch someone impulsive that's in a rush to get one. Do I think it's a dreamer price? Yup. Do I think there is someone out there that might if you wait long enough? Probably.
In terms of actual advice should the seller read this, after shipping fees and potential import charges you're probably looking at a similar cost from TG as you would be Patrol Base (you might get lucky and skip the fees but we'll go with 'worst case'). The arbitrary starting point of 60-70% of £230 (it's useful as a baseline if nothing else) falls at £138-161. Considering they're seemingly relative hard to get your hands on at present, if it were me I'd likely list it for £180 including all fees and postage.
