@elilla Lidl had a particularly strong version of those racks for 20 EUR a few years ago (much less flimsy than the typical 25 EUR fare here!) with, unwisely, flat-rate 5 EUR shipping. So I ordered like 10 of those racks at once, and they ended up shipping me all 250kg of it by parcel mail.

I've pretty much had no storage problems since, and just occasionally pull out a box from the stack and set it up
