Okay, we might want to mention which area these shops service, as some will only ship to certain countries, in order to make finding the right one easier.
In Germany
Simones Hammerladen - Tauchshop Chemnitz mit Versand für Tauchen und Wassersport is a good choice.
I found that
Apnoe Spearfishing Freediving Shop O.ME.R BEUCHAT PICASSO IMERSION don't offer much choice, but the good stuff is there. Mind that they sometimes are very sluggish with their communication.
I assume that both will ship at least to any European countries.
