PLEASE NOTE: If you would like to customize your order, you may do so by typing in your information under the "add an order note" section in the "checkout" pane. For example, if you wanted 3 of the bear postcards and 3 of the whale postcards, (versus 1 of each design) you would indicate it there. You are still limited to six for $5 (unless you multiply your order!), but you can mix and match using this method. 

Clicking on "checkout" will take you to this window, pictured below. Simply add your order note, as depicted by the red arrow.
