Hi,
Are you using URL mapping and if not
you need to send the page name

http//:www.buygoods.com/buy.aspx?email='"+me.txtemail+"'
and retrieve it as
string str=request.QueryString["email"];

[mail2saion]

change the line to response.redirect("http//:www.buygoods.com/buy?email="+me.txtemail)

And check the destination page addressbar that email contains the value.

But never try to pass secured info cause query string is not safe. To pass secure info you can try with form submit.
