I have heard of several more newsagency suppliers announcing they will soon have fidget spinners. Each one of these is too late to the party. Had they taken notice at the Nuremberg Toy Fair, the New York Toy Fair or any of the other international fairs months ago they would have known this was coming and been stocked up ready to go.
In capital cities it is time to ensure you have cleared stock rather than stocking up. Sales for this craze have slowed and the key is to not be left with stock, like many were with loom bands.
