sideshow savage edition predator legendary scale busts

just a quick question on savage edition predator LSB , i'm new to collecting these and items from sideshow and was wondering how these work as the first one was 100 edition are they just flash sales and if so how do they inform people, newsletter, facebook etc or do the put them up for pre sale and first come firat served, bought the first pred via ebay at inflated price so if they are going to do savage edition of upcoming preds i would like to avoid that route, thanks in advance

They usually put those types of very limited run items up during SDCC, Spook(which is going on now), or around Christmas. Not much warning, but there is some, just check here often for updates.
