Well I got a semi response from Kodak (Mexico). They said AZO RC is only distribuited in Mexico and that Kodak Mexico does not ship anything to the US (yeah right!). OTOH they mention that if there was interest for this paper in the US perhaps they could ship to a "distribuitor".

Typical of Kodak, they said that only "distribuitors" here in Mexico can give me prices, so I will call around next week to find out what are the prices for different sizes.
