Sam's Club and Costco rationing bulk rice

From CNN.com:

(AP) -- The two biggest U.S. warehouse retail chains are limiting how much rice customers can buy because of what Sam's Club, a division of Wal-Mart Stores Inc., called on Wednesday "recent supply and demand trends."

The broader chain of Wal-Mart stores has no plans to limit food purchases, however.

The move comes as U.S. rice futures hit a record high amid global food inflation, although one rice expert said the warehouse chains may be reacting less to any shortages than to stockpiling by restaurants and small stores.
