I am sorry that you got used to interpret contractors' replies as a bullshit. Personally I told you how things are getting on indeed.
If someone spend 11 000$ for the script - he probably has a reason to cry this brand, since he supposes that became a part of some so-called "luxury society".
However sometimes rational people prefers to pay
the real price for really efficient script, and zero for the bubble script's brand-name. This is a market and you are free to choose your way.
If you ask for a demo - it is provided on the aWIZ site, and furthermore I gave you accepted sample above.
If you will ask can the traffic brings to overloading - I can say that not earlier than any other script: aWIZ is quite stable and tested by the years.
But if you name my responses a bullshit and demand a unpublished info - ...with all my respect to you, probably will be better to choose another product. Good luck!
