Desperate for resin

Exactly what the title says, I am desperate for resin. I need to know where you buy it. I did my research and i did ask my friends but all of them says the same thing which is to get it from art friend. I've heard about it a few times but i don't exactly know where it is. Even f i do, most of all the resources (friends and teachers) claim that there are actually very expensive.But i need them. I've been so inspired but that Instagram user where she makes really nice earrings. Do you think they sell them online? i'm too lazy to travel. URGHHH.

It's so pretty right??????? but i want to do it on my own. :/
