Normally this is the kind of thing Amazon falls foul of. But now that Amazon owns ComiXology, maybe it will become more common?
All-New Ultimates TPB Vol 1 is listed on ComiXology at the rather low price of $1.99 or £1.49. A promotional price? Possibly.
But then when All-New Ultimates #1 is listed at £7.49 or $11.99 you think that maybe, just maybe, someone may have got the two confused.
