Quote - That's the part where I get confused. I purchased the Poser 6 CE upgrade and now have P6 CE on my system also recieved a coupon code for P7. Now do I have to pay for P7upgrade or is it free? I already spent  $149.99 on the P6 upgrade and don't really have anymore to dish out.

Very simple :-
Put the P7 upgrade into your cart and apply the coupon, the cost will show as $0.00
Checkout.
Sit back and wait for release.
