SEEED SD Card Shield and the ardunio mega 2560

Right I realize that on the wiki it says that but on the package it gives no indication that it is not usable with the arduino mega. How am I suppose to know if I’m at the store that it will be not compatible with my device? I would have to know that the wiki existed before having even bought one of your products. It’s a bit misleading.

The touch screen I have only seems to work with the Mega 2560 (I think the wiki is fairly hard to decipher at times). The SD card shield that I have only works with the Uno meaning that these parts are useless in combination with each other. Am I correct in thinking that the TFT 2.8" touch screen only works with Mega and the Seeedunio mega?
