peps in the us

[jubilation]

I have about 2 sources both expensive, one 1.02$ per iu other .74c per iu. I know "if you cant find sources don't buy it" but I've been looking for 4 hours online and cant find any actual sources that aren't just overpriced vibe code websites. I want to find it somewhere cheaper so it'll last me till December when i get my license and can finally get a job, I have about ~300$ to spend asking if there are any sources that have it that cheap for 700iu (or asking what i need to look into to find those)
