Please stop the hysteria. Yes it seems that the price is more now than when I purchased around mid May.
I think they realise that they have a competitive product.
I bought my 32Gb Komputerbay 1000x card (from Amazon) for £51.00
I just did a search and it has gone up in price. But I wouldn't say to extortionate amount.
Now the price is £55.00 (with delivery).
Make your own mind up if people should be outraged by a card that still represents excellent value for money.
I.M.H.O. of course

EDIT: Also I think people buying in US $'s should really consider themselve's lucky that they don't have to pay the inflated prices we have to pay in places like the UK.
The Komputerbay 64GB card is advertised as £96.00 in the UK if you convert that to USD that comes out at $146.22
(I also had to pay considerably more for my 5DMKII. The list goes on. I won't bore you)
