Look, they could use the argument "Just buy more storage chests!" if um, well, you know. There is no freaking way any sane RoM player is going to stick item shop goodies they paid RL cash for in a disappearing housechest, just to get a ticket back a month later that states "lololol sure, you'll get those 200 puri's back just as soon as we have screenies and a letter from God saying they existed! lololol" That's assuming you even ever get a response back at all. I have one guildie (bless him, Palenqueans you know of whom I speak) who lost I dunno how many hundreds of dollars worth of item shop stuff from his 20 or so missing house chests, and he's still lividly waiting for the lol!ticket response.
Another of my guildies likes to say "Gee, Frogster, it'd be great if I had room to BUY MORE STUFF... THAT'S a winning sales strategy if I ever saw one!"
It's like it's so obvious that we should have basically infinite spaces for cash shop stuff... yet we don't. Marketing, so easy a caveman could do it- 'cept apparently they can't.
