Amazon.de was sold-out around February-March 2020 and never really recovered. Currently there's only third party sellers which sell FFP2 masks in there.

But masks are widely available in pharmacies and specialized stores. I'd try to find a store selling occupational safety items if I were you.

FFP2 masks are everywhere in Germany, even my local Döner Shop sells them and every supermarket has brand ones either as single or pack of ten. I didn't buy the last pack from amazon but direct from the company (medisana) because amazon afaik throws all (counterfeits or originals) in the same bins and you can't be sure what you get.
