Here is a weird one I got from Terry Hoknes at www.hoknescomics.com.
Steven Universe is hot. The comic that is. The low print run kids comic is in demand.
Pretty much every copy, every cover, is selling for multiple times cover price. The later issues seem to be going for more than the earlier ones. I found a copy of Steven Universe #6 and within minutes of listing it, it was up to $10. The Same Issue sold for $61 last month. Sure, the prices on some of the books can be all over the place at times, but it seem that these are hard to come by and do sell well.
