(US) selling more OGL books briskly lately

I noticed over the weekend (US) sold out of their in stock OGL Steampunk book. They had two copies on Friday and now they are gone. They sold out of OGL Horror this weekend also. They had one copy on Friday in stock. I think this is a good sign. OGL Wild West stands at 4 copies left and OGL Ancients seems well stocked. OGL Cybernet has three copies left.
OK, I noticed that two more Steampunk books have been sold in the past several days. If any of the higher ups at Mongoose are reading this, Amazon needs more books from you. I think that the OGL books are really picking up lately......
