i've bought an ice bori and a nightsteed with a name i REALLY liked to complete a creepy pet-themed side i had. (which was some hilariously low price, like 50 cents or something)
i've also bought 2 rw pets, one for my personal ownership and one to try and trade for a uc. no one's looked at me twice for my uc trade fodder rw pet, so /shrugs
i also didn't pay much for any of the above pets. buying rws/rns is a GREAT way to get another uc trade chain started on the cheap. if you're too broke to buy your uc dream pet here, just buy a rw and uptrade while you rs/ss/whatever it is that you do. s'what i did.
