This is pretty simple. Simply tap on the Zen shop tab on the menu and use your track pad to scroll right. This will switch you over to a regular shop menu, but the items from the page will remain the same. Scrolling again will force you away from the Zen items, and please note this method only works for the first page of Zen shop items.
Now, for people with a hardware keyboard, you can access the other two pages of the Zen shop by clicking the tab, clicking to the desired page, then pressing the 3 button on your keyboard.
The items all way they sell for a high amount of gold, but the real prices are much lower. Some items wont sell in stacks, and buying gold gives you an item called gold in your inventory and it doesn't work so don't bother with it. Just takes up space and you have to use another glitch to delete it.
