As the Square Market has yet to open outside the US, I have created a temporary Paypal button for each of the 2 new items in the EE store. You may click on "overseas purchases" in the sidebar, opening a page on which you may buy either book through Paypal. You'll be given a chance to pay with your Paypal account, or to click that you don't have one, which opens a window allowing you to use your credit card.
The price is higher on Evil Editor Strips Again, because of the expensive overseas shipping. As The History of the World in Tweets is digital, the price is the same $1.99. If you are overseas and there's something else in the Evil Editor Store that you want, let me know and I'll create a Paypal button for that.
