3d Printer RESIN Answered

Hi, i'm planning on buying a SLA printer, but i want to be sure that i can get a good amount of resin at a fair price, i found some places but since i'm from Bolivia-Latin America, the shipping and buying from Us Europe or Asia it becomes quite expensive, sometimes like +65% to 80% of the product itself.
If someone knows a DIY resin, or some good places that doesn't cost as much per L or Galon plz let me know and share it with everyone else.

Anyway, thx a lot for reading and take your time, i hope i can get an answer.
