Exactly. I mean, don't get me wrong, some of those items were pretty awesome (I especially liked the Castelia City model) but the novelty wears off after you've purchased everything. I just wish they had made more secret base items in this new Hoenn region. Or hey! Similar to how each 3DS system gave you a different Friend Safari in XY, they should have made several pre-determined item listings for the Lilycove sale, and your 3DS system determines which items you get!
That might be going a little too far for a relatively minor part of the game, but I see your point lols. And yea, I loved some of those decorations as well, and while there were a bunch of new Secret Base items in this game, they were mostly found in Fortree City's shop, not in Lilycove's. Not that that's a bad idea, they expanded that element in that city, but didn't for another. Having both item selections boosted would have been pretty neat to see.
