Made an order for some watercooling liquid from www.sharkacorp.com . After I had made the order I paid wih paypal, and they then (after about two days) emailed me to say that the postage I had paid was not enough (although it had said that i had paid enough at the time I made the order) and that the two product i have ordered dont mix together (althogh I emailed them proir to the order and they said it would). They told me that I need to pay more for the delivery which means that i would be paying lots more that other places so I asked for a refund. They have not emailed back. I have sent numerous emails to them all with no reply so. I have been waiting about two weeks. They replied to one saying if I pay mor ethey can ship both out soon, yet I want a refund! So, if you see a good deal on there, dont get it, it is cheaper else where...trust me
