Preventing Price / Form Manipulation of Price

Hi, please let me know if there is another thread about this
topic.

What's to prevent people from using simple javascript
techniques to
change the price of an item before continuing to Google
Checkout?  I'm
sure this has to be covered somewhere, but I can't find any
mention of
it.

Thanks -N

I just thought of something...  You could put a hash in
'item_hidden_data_n' that will only resolve if the
name/price pair
match.  This seems a bit kludgey however.  Any better
solutions?
