Register

Registration of either ChairGun2 or ChairGun Mobile costs just 10 UKP. You'll only have to pay/register each product once - the CodeKey will remain the same through any future updates, versions, etc. Most of the monies collected will be passed on The Dog's Trust to help with their worthy causes - perhaps to re-home fine young dogs like Max.
You should be able to purchase registration(s) using the PayPal mechanism below. Credit card details are OK if you don't already have a PayPal account.
