Knowing amazon.fr, pre-order will probably come down to €24.99 in a near future, hopefully.
The amazon link in the opening post doesn't link to the page where the artwork is the up and the pre-order price is €26.99, btw. It's on this page instead.
For the lenticular steelbook of an animated film with Blu-ray 3D, Blu-ray 2D and DVD, €25 would be a pretty good price.
I will get that one, and also the French Epic lenticular (€23, released 9th October), they will go well together :
Epic doesn't have a banner, as you can see (and it includes 3D despite it not being indicated on the front). Maybe the banner on Les Croods is on the J-card.
