Yeah, I think they only ever really put things on clearance when the line itself changes name. They don't seem to recognize the difference between waves, so much.
That would backfire. Retailers would see one wave as not worth their time.
It's a puzzle. Retailers want a line that lasts multiple waves so they know they'll have a while before they have to think about switching over to the next new thing, but they also want to consider those multiple waves as essentially the same thing. They don't care if Hasbro wants to move on to wave 7. Wave 1 is still just as good as ever.
It does make sense when you consider other toylines. Parents looking for Spider-Man don't know whether they're looking at a wave 1 or wave 2 toy, and will do absolutely everything in their power to refuse to notice a difference if their kid asked for a specific one. Parents and retailers agree, it's all just Spider-Man. Transformers just doesn't fit that retail model as neatly. Hasbro tried with Bumblebee, and retailers loved it, but we hated it.
I just got a kingdom blaster from the liquidation retailer not far from here. Brick and mortar for anything other than necessities has been miserable since the pandemic.There's one place in town that sells Transformers now and they still have Kingdom toys up last I checked.
Even if Walmart wanted to pay that much attention to what they're ordering, they can't do that for every product line they carry. They're just too big.
I miss them too! The giant walls of GI Joes, Star Wars, and TFs were almost hypnotic!I miss the 80's toy aisle. The days where one line got a full 30 foot section. Now most are lucky to get 10' of space.
