How large is the floral foam market?  How much wet floral foam does
smithers oasis sell? How much revenue does smithers oasis make in one
year?

You might want to check Hoover's (http://www.hoovers.com/). Hoover's
is an invaluable tool for researching corporate information and
provides a plethora of data just about any company.

A search for "floral foam" on Hoover's revealed MJDesigns, LP, a
leading manufacturer of obscure arts and crafts supplies, including
floral foam. Their revenue in the last year totals close to $40M.

Unfortunately, information on Smithers-Oasis is only available with a
subscription. A search did reveal three Smithers-Oasis branches in the
US including the headquarters in Cuyahoga Falls, OH.

Hope this helps!
