Conditional logic beyond show/shide

Hi,

I have this query about gravity form and would like to know if it can be done. I have been reading about conditional statements and as far as I can understand its mainly restricted to show/hide. Also I cant see any place where the submit button can be handled explicitly (it seems to come automatically)

Here is my specific problem
I have a list of 3 products (say A, B & C), the first product has a differential pricing so I have 2 products defines and hide/show based on the tick box which shows the threshold value.
Now the condition that I want to build in is that the user has to buy product A OR a min of 10 (B + C) products. Also as shipping is not applied separately total value has be an ‘x’ value (which is 10no.s of B or C)

Is it possible to set this up is Gravity forms?
I tried in the demo site but could not.

Thanks in advance
