Order small bottles or sample size bottles. That way you won't end up with a really big bottle of something you really don't like.
If you get something you don't like, you can sell it or trade it with people here on the forum. Or you can give it to friends. Or you can hang out in the PIF (pay it forward) forum here.
Keep in mind your taste buds change a lot and frequently when you quit smoking. I make that statement on the assumption that you have, or will quit smoking someday. These changes in your taste buds will keep your juice preferences jumping all over the place. There is no way to fix it. It just takes time for your taste buds to settle down. I've not heard of any short cuts when it comes to healing the taste buds.
JCNewbie said it well. Ask 100 people their favorite juice and/or juice supplier and you will end up with 70 to 90 different answers. Taste is subjective. I don't care for chocolate. Others can not get through the day without chocolate. You get the idea.
All the best to you,
Happy Vaping,
Paula
PS - I am sorry I did not address your question about price. I don't pay attention to price when it comes to my juices so I can't help you there. If I like it, I pay the price.
