My family lives on a pension, so my mother would forbid me to do unnecessary stuff with my cash which is unfortunately donations.
I was once jealous of other users who had supportership, only to finally end up becoming one when Oryx (fyi she's an ex-PokeGen mod here) won a supporter prize in a forum event and decided to give it to me as a birthday gift, all because she knew my birthday was the day before hers.
I only got my Platinum Tier in November last year when PC had limited-time cheap Platinum Tier supportership on offer, and Cloyster couldn't resist to jack me up so she donated in my name.
If I was able to donate on my own, I would have done so. Though because I'm Platinum Tier now, I'd mostly just do it on other members so they can enjoy VIP life as well.
