2kg is a lot Ive hardly touched the bag but its doubled in price since 2019.

I bought 1kg from those Wholefood people above back in April. They were much cheaper than anyone else. I paid £4.75; it's now £7.25

Edit: I got free Prime delivery; looks like they want £3.45 delivery now.

I've bought some from Wilko on the High St, but mainly from eBay.

I also have a big bucket of Sodium bisulphite (pool ph minus). This stuff

Slightly stronger than citric but not much? I havent really tried for derust or descaling. Many diy shops sell it, b&q, the Range etc..
It works for anodising but I prefer sulphuric and unlikely I will use much of this tub.
