selling and buying as well
i waited for some collectibles to rise up in value then sell them lol
i had a cycling town before and sold tier 1-2 villagers for some time
i have tons of IGB that i dont rlly use in the game so i just sell them for TBT to anyone who needs some
i also used to have a sig shop where i made signatures for free, so donations were a part of it
there's also giveaways and as far as i know Javocado made the most TBT giveaways around here so we gotta thank him
lastly, simply posting lots around the forum can get you a handful of $$$
most TBT i ever had was 56k, i never passed that lol
