As you can see in this image, some of my donation letters refuse to stack stressed Initially, I thought the problem was that perhaps when I bought them off the marketplace, one letter had been purchased prior to the 15th of the month it's for and the other had been purchased afterward. So I figured to solve the problem, I just needed to buy another letter that did stack, then sell off the one that didn't. I did that with success at least once {don't remember for what month}, but as you can see with the pink envelope there {which would be the May 2010 letter}, it -still- didn't stack! scream stressed I even bought a fourth one hoping that one would stack with one of the other three, and it still didn't. 140k out the window trying to get my letters to stack stare stressed
*hopes the May 2010 letters increase in price soon* stare
