Welcome Omar, it would help to know where you are in the quitting process (and what vape equipment you are using) to help get you started and answer any initial questions you have.
As far as juices (depending on your location) some Vape stores will let you try sampling their juices to see what you enjoy, as well as possible juices for purchase. Similarly, many online vendors will sell small sample packs of juice so you can try several without too much outlay of funds. I think finding someone who will just "send" you juices for free is likely going to be difficult, but you can minimize costs while finding some juices you enjoy (hopefully) using those two methods.
Welcome to ECF and I hope you enjoy your stay here. Please also ask any other questions you have, we want you to succeed in transitioning to vaping safely and as easily as possible.
Welcome
Anna
