Do NOT waste good money on WhizAnalysis!!! They are unable to keep up with changes on the eBay website upon which the software totally relies - making it virtually useless. The support is non-existent. They will promise you a refund of your $279 - then send nothing at all. A much better alternative is AuctionIntelligence. Their program is easier to use and their support is excellent. YOU HAVE BEEN WARNED!!!
