I wouldn't buy from them, buy from a retailer or etailer you know. That site has no physical address, and no commercial phone number (to check their area code). Your risks include:
-- Losing the $94.99 if the software is not genuine.
-- Installing software infested with trojans, viruses, and other ugly surprises.
-- Giving your credit card or other payment info to fraudsters.
Saving ~$30 is not worth the risk to me. But it's your money.
Don't trust a place that has no physical address or phone number that's for sure.
