At least they're a couple of chapters, some of the books I've looked at recently are 4.99USD for 15 pages, and that 15 includes the cover, the copyright, & The about the author.
So you're thinking you're paying 5 bucks for 12 pages (NOT), and when you break down and do decide to get it, you routinely find 4 or 5 pages of well if you liked this you might like these too.
I've taken to calling anything under:
100 pages a Short Story
40 pages a Short-Short
20 pages a Short-Very
10 pages a Short-Very-Very
and if it ain't at least a short story I'm no longer spending my money.
I can get something that low quality just repeatedly feeding an AI myself, and I expect I'd get better grammar, spell checking, and likely a better story. Just ask the KLRXO fans.
