Hey guys and gals! So far my favorite vape flavors are Reds cowboys, congress (from v2 carts) and Sweet carolina from ivape.net. Now im hearing a lot about this RY4. The review i read on here was RY4 from a site that has a waiting list. It seems like im going to be waiting a while. So, can you kindly advise me of a site that has some good RY4 and whats a good tabaco flavor thats not as sweet as ivapes carolinas. Also, do you guys let it sit for a few days before you vape it? Thanks again!
