LOL, Nicoticket is one of my favorites, too. They do 20% off flavors of the week now, so watch for CLS to pop up and then you can increase your stash! Get on their mailing list, if you aren't already so you can catch all the specials and new releases. They are also available now at Giant Vapes. In general, if you like ONE flavor at a vendor, you will most likely like the others - the base mix will be likely the same. At NT, for example, the base and their "steeped in house" vanilla are in many of their offerings, so if one agrees with you, the others probably will, too. If you like CLS, you should try their Absolut Creme Brûlée. It's FANTASTIC!
Of course, there ARE other companies, and custards are very popular right now. I just hate being disappointed with an entire bottle for a few dollars. I don't save anything if the whole bottle is a waste! YMMV.
