AVE does have some good juices, but I dont think their a good vendor at all for a new vaper. All their juices are VG and most of them are very thick. 100%VG juice is much harder to fill a carto with bc its so thick, and its a LOT harder than a thin mostly PG juice. Learning to fill cartos when your just starting out can be difficult, and uses a thick VG juice will just make it harder. I do like Bobas Bounty from AVE, but I find you basically have to use a syringe to fill a carto with it, and some newbies either dont want to use a syringe or dont have one. You can drip fill, but it will take a LONG time bc the juice takes forever to settle into the carto bc its so thick. Also you then risk ruining a carto bc you didnt wait long enough for the juice to settlew to the bottom and you burn the carto. So I think youd be much better off starting with a vendor that you can get mostly PG juices from, like 80/20, 70/30, etc. Juices with 30%VG or less are much more carto friendly and soak into the filler a lot easier/faster/better, and using a thin PG juice will be a lot easier to learn how to properly fill cartos with.
Dont get me wrong, AVE is a good vendor and while they dont have a ton of juices, many of them are very good, I just think their better for a more experienced vaper, instead of someone thats just starting out. Also, AVE juices are expensive, which can really add up for a newbie that wants to try a bunch to figure out what they like. And if you do want to try a bunch, youd be much better off going with a vendor that offers sample packs, so you can try a bunch for fairly cheap. AVE has samples, but their not cheap, and they dont have sample packs, which will give you a better deal.
Check out BlueMist Vaping. There are a lot of good juice vendors, but BlueMist is awesome for both experienced vapors and new vapers. I think they are perfect for anyone just starting out bc they have such a big selection to choose from, and their prices are dirt cheap.
BlueMist has over 250 juices, and their prices are $5 for 10ml, $10 for 30ml. They also offer sample packs and I highly recommend getting a few to start. They offer (5) 3ml samples for $10 or (5) 10ml samples for $20, and they let you pick your own juices for a sample pack so you can try the ones you actually want to try. I recommend getting the 3ml samples to start so you can get a few sample packs and try a wide variety for cheap. All their juices are made fresh, and you can get all of them in either 80PG/20VG or 100%VG. I recommend 80/20 for reasons above. They also offer extra flavor shots for .50cents more, and if you find a juice you really like, you can get a 180ml bottle for only $30, which is an awesome deal.
EDIT: Oh and BlueMist is having a sale right now for 20% off until the 26th, which makes it an even better deal.
