They were never offered for sale in-stores, they were mail-order only. My brother and I had the one in the upper row, far right, but I don't remember how we got it...I think he may have traded a friend at school for it.
I, on the other hand, totally sent away for this from GameSpot (back when they were VideoGameSpot):
If you want to watch 45 minutes of VHS-quality Tomb Raiding glory though, some other enterprising soul posted it to YouTube! Rejoice and be glad, ye fellow Lara-holics!
