Why is the price of local flour so high?

Dear Editor,

I read the half page ads which indicate that the National Milling Co. of Guyana Inc. (Namilco) has taken the unilateral decision not to reduce the price of flour they produce by 16% being the VAT element removed under the provisions of the 2008 National Budget.
I agree that there have been rises in the world market price for wheat so as a result there must be an increase in the price for the local flour. For some reason though flour is still an expensive commodity in Guyana when even compared with some smaller Caribbean islands.
