Collecters can talk about about economy, oil prices, cost of materials all they want. The number one reason Hot Toys charges the prices they do is because they have a rabid fan base who will buy whatever they put out because it says Hot Toys on it.
The Economy and the ever falling US Dollar has everything to do with why we are paying higher prices for Hot Toys,other toys,or just Basic necessities such as Food and clothes.
More Debt and money creation = INFLATION on everything we buy
whether its petroleum,materials,plastic,paint....it costs more to buy those things to produce because the Dollar has lost its purchasing power
