I already had the breathable ground sheet and the Eco adjustable bin delivered but out of nosiness I popped into Aldi as I happened to be passing nearby.
Couldn't leave empty handed

so bought 2 litres of bowl cleaner.
The store had plenty of everything, no big rush on caravan gear at this store.
I took an interest in the 23 litre plastic jerry can, but the caps look larger than those on an Aquaroll, it made me wonder if a mains water kit with the stop **** would fit it, I would need to take a cap from the Aquaroll and compare it in-store. The position of the side cap does not look to be ideally placed for a mains water kit.
I don't think I will bother with it, though the waste water container would work quite well.
