Where to get basic sunscreen for less than 150 MAD

I'm trying to buy sunscreen and am shocked by the big prices. In Germany you can get a basic sunscreen bottle (non-brand, discount) for 3.50 EUR ~ 30 MAD.

I've been to 2 stores in Tamraght and the cheapest they had were dodgy looking ones for 180 MAD. I said I was not going to pay more than 100 MAD but they said no chance, so I left.

Even Decathlon sells for 1000 MAD/litre. Is that just the market price? Maybe Moroccons just don't use it so it's not supplied in sufficient quantity?

Asking out of curiosity and as there will be others in the same boat. Maybe there's a good option I haven't found.
