Personally, I’ve bought from Mark’s Models (as recently as yesterday) plus several “box-shifters” in England, plus private purchases, and fleabay in the past.
While I have a massive preference for buying from local firms, especially now when they need all the help they can get, friendly, prompt and efficient service with timely deliveries and good back-up in case anything might go wrong, takes priority over price.
Having said that, no matter how much I wanted something on fleabay, if the seller wanted some of the stupid prices occasionally seen, I would politely invite them to insert the item in themselves.......
