question about yarn

[Lieuvena]

Hi. I was browsing through yarns on Etsy and I came across some that say the weight is "aran to bulky". I really like some of the colors, but I was just wondering what you could knit with it. Is it actually a practical yarn? Also some say lots of beehives. What is that? I can tell that the yarn is very thick in some spots and thin in others. It's also plied with thread. Is that a good or bad thing. Thanks for the help.

If it helps here is what I was looking at:

One more question, is that price considered a good price? I understand the work that goes into handspun yarn, so I totally don't mind, I was just wondering if there was any sort of average. Sorry, but up til now my source for yarn has been Walmart. I'm feeling a bit more confident and trying to branch out and just don't know much past that.

Thanks.
