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 instead.
One last thing: Adept Press isn’t anyone but me, and I have one fulfillment service, which isn’t anyone but one other person. Your order registers with me through Paypal; I pass the order to the fulfillment person; and she mails 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.
