Does Warehouse Stationery have the worst fulfillment system?

For the second year running, I have received on my doorstep a bag with a single 30cm ruler.

I've also received one bag with two green pens, one bag with two whiteboard markers, and a box with the rest of my children's stationery.

This is slightly better than last year, where I received 7 packages. But surely this is a terribly unsustainable business practice? I only paid $6.99 delivery too.

(I ordered it for delivery because I couldn't get to the shop in time, our school's app sends us directly to WS to order, and I'm not sure if the WS branded literacy and maths books are different to other brands. Otherwise I would've gone elsewhere)
