No shops around here got the Thanos #13 1:25 variant or else I would've grabbed it, it's one of those series that just a few shop regulars were reading during Lemire's run so I'm guessing that even with Infinity War on the horizon, nobody went heavy on it.
They all finally caught on and went big on the 2nd and 3rd printings but still not so much with the 1st prints of the entire run at all, not even the last 2 issues when the series was established as a hit.
Point being, the lenticular will slowly rise in price, (currently $50-$60 in 9.8 which isn't bad) people are going to want complete sets because it's one of the few bright spots from Marvel in the last decade
