I can understand it if manufactures have stopped production because they're waiting to see what will happen with ban regulations. Since there's no point making a product you can't sell. This will cause prices to rise, since there is no supply. However, someone pointed out in another thread that manufactures have announced that they intend to raise their prices because they've seen how much some stores have raised their prices.
This is not a result of supply and demand, it is a result of greed. Some stores gouged so much that the manufacturer thinks they can get more, which means the distributors will charge more, which means every LGS will have to charge more to cover their costs.
Now I know, with time, the market will correct itself, provided people wise up and stop paying inflated prices. Until then, your choices are simple: pay more or try to wait it out and hope prices return to normal.
