Hello Don,

In fact, being a freelance photographer and photo chemistry researcher
as secondary job (I almost don't make money with it), I am a customer at
Sigma-Aldrich. You can order by phone and enjoy a next day delivery, at
least in Belgium.
Very often you may have small quantities.
For some products as Pd and Pt salts I do not recommend them, it is too
expensive. There I think Dick Sullivan holds the market. On the other
hand, you can buy Ammonium Ferric Oxalate by kilos for peanuts.
