Schylling sold through roughly six months of NeeDoh inventory in six weeks this spring, and the ripples are still moving through the supply chain. What we see in the registry, week over week: common variants reappear first and stay longest, novelty shapes come and go in short bursts, and seasonal runs never really restock at all — they ship once, and then it's resale or nothing.
Big-box restocks arrive on truck days, hit the shelf during overnight or early-morning stocking, and are picked over by opening. The window is the first two hours the store is open. Online inventory usually updates before the shelf is even built, which is why rule one is to check the app before you check the aisle.
Stock cycles are also uneven by variant. The Nice Cube cycles through Walmart and vanishes same day. The Gumdrop has the widest retail coverage of the hunted variants and is your most likely walk-in find. The Jellysquish is tracked by every restock service on the internet, which makes it a decent barometer for overall craze heat. Seasonal specimens like the Advent Calendar should be bought the moment they appear at retail price — marketplace listings were already near double MSRP five months before December.
What a fair price looks like
Most standard variants retail in the single digits; the oversized and multi-pack specimens run a bit more. The registry lists a typical retail range for every specimen we track. If a listing runs 50% or more above that range, our survey flags it as scalped, and you should treat it the same way: close the tab and wait for the next truck.
When resale is actually defensible
Only for S-tier grails — the specimens that sell out within hours of any restock and carry sustained premiums. Even then, buy with eyes open: run the authenticity check on arrival, and remember that a grail bought at retail is the collector's story worth telling. One bought at 4× is just a receipt.
