Comparison prices incorrect! Nextag/Shopzilla more accurate comparisons at more stores! Update your information!

I downloaded PriceAdvance and have found that in 4 out of 5 comparisons the information was incorrect. It is becoming consistent with your site. For instance, today I have been looking for the Fisher Price Fun 2 Learn Computer Cool School (Mfg. Model M6635). Your "popup" information was incorrect, showing Kmart the best price at $52.19, the Kmart website price when checked was $57.99 (Kmart item# 004W688993110001 Mfr. model# M6635 ), amazon.com price-$53.99; Sears $64.99 when checked, Sears doesn't even have it on their site and neither did Walmart even though you show there price as $54.88! Nextag and Shopzilla, sites I have used prior to loading yours, both had the correct prices AND had online stores that were lower and available than ALL of yours!

How often do you update your website? Why are other sites showing more stores with better pricing? Are you only able to show certain online retailers? How many stores can your "popup" show?

Thank goodness I am a veteran comparison shopper! Had I used your imformation, I would have wasted over $10.00! Sorry, but that is not going to get you a lot of good reviews!
