Buy From Amazon!
First, if you prefer to purchase them directly from Amazon, you can find a link on each product page that goes directly to the Amazon product page. I suggest using these links as it's not super easy to find them on Amazon for some reason (searching by ISBN is your best bet).
Buy From Us!
You can of course buy them directly from us, which we prefer since we make more per book. I created a stock availability system so customers can know if I actually have copies to ship immediately. Books have two states, In Stock or Reprinting. If says Reprinting, it means I have more stock coming and allow 1-2 extra weeks for delivery. Or you can simply go buy it from Amazon.
Right now, most of the print books are in the Reprinting state, since I haven't actually received my initial stock order yet. It you want a book ASAP, buy it from Amazon. If you can wait, and want rpgobjects and the writers to get the maximum return, buy it from us. Either way, we appreciate the support.
