This postcard is approximately 23.5 cm long which is the length limit for the first two types of postage. Once it is packaged it will exceed the limit so unfortunately the postage will have to be $4.60 . However, quite a lot of postcards can fit in this size of envelope so multiple purchases would only require one lot of postage. Any extra postage paid with Ping will be refunded. To avoid Ping charging you extra for multiple purchases, choose "postage" for the first one and "pick up" for subsequent ones. I will be listing more of these in coming days.
