Inquiry about pick-up buff pets.

I was wondering where exactly would we be able to pick up the items and such to turn our pick up pet into a pick-up buff pet. Though I've been on here for some days now I'm still unsure on what merchants will be selling what. Like the NPC in Saint Morning that sells costumes. I was also wondering if there was another that sells the more rare costumes too, btw? Like the Demon Set [ not the Demon Lord set ], or the Bushido Yukata 2010. I'd really love to get those if they're on here. <33

turning pick-up pet to a buff pet is through donation.. at 100 PhP..

and about the Bushido Yukata.. it's not yet implemented ingame..
