I've bought around 40 albums or so through Bandcamp in the last couple of years. I think it is a good platform, and I like that I can get FLACs instead of Mp3s. I think artists really need to think over their pricing, and think about how much they are likely to sell at the prices they set. If something is out of print, or hard for me to obtain in my corner of the world, then I might pay up to $10 for a full-length album. However, I don't think that is a good pricing strategy for most artists.
I've seen established artists sell their albums for $5-7 and I think that is the "sweet spot". If they want to sell them a little cheaper, say $4 an album, that is fine also. When prices start creeping up, especially if it is an artist that is relatively unknown to me, I'm much less likely to make a purchase. Unknown artists are better off charging no more than $5 for a standard full-length album, and if they want to get some purchases, they should offer some tracks or maybe at least one album as a free or "name your own price" download.
To keep things in perspective, I recently bought a Thomas Koner album for 8 Euros, which works out to be just under $10. It's worth noting that was a double album of about 2 hours running time that also included a video. Artists that are charging 14 Euros for an album that only costs a little more to get an actual physical CD of are dreaming. I'm guessing they are wondering why Bandcamp is not working out for them...
My two cents...
