The links go straight to the “buy” page at the Gaming Un-Store, with Paypal links from there. If you want to read more about the games, then use the menu to the left. Also! All book sales include the PDF for no extra charge.
One last thing: Adept Press isn’t anyone but me. Your order registers with me through Paypal; I go to the post office once a week to mail the books. All of these steps are totally not automated and are subject to delays based on real life. The good side is that any hassles can be fully corrected.
