Allen & Ginter Obsession?

Always when its this time of year I wonder why we are all so obsessed with Allen & Ginter. Most years we get essentially the same set as the last yet so many people purchases cases of Ginter. Don't get me wrong I love Ginter, but I can't help to wonder why if its usually the same stuff (or very similar) every year. My only explanation is the resale value of the hits, but on the other hand many hits are very cheap (the many many jersey cards). Another reason maybe the red ink autographs or the non-baseball players autographs (which also is criticized by many). I may never know the answer, but I do know I will definitely be buying a box in three days.
