I purchased last Wednesday (20 July 2011) a voucher for SCJP EXAM on the website www.whizlabs.com.
Their website says, that you'll receive your voucher in an e-mail within 4-5 hours after you complete your purchase.
After 24 hours, I haven't received any e-mail from them. They could at least send a confirmation message...
So, I opened a dispute on paypal and wrote an e-mail to whizlabs in order to clarify the issue!
But all I get from the whizlabs support is an e-mail with an apologize and they will call me, when they send me my voucher...that's just rubbish.
I don't know, but the whole thing looks very suspicious to me.
