50 pound surcharge on packages.
While the shipping cost per pound has gone up across the board, there is now a special surchage for packages of 50 pounds or more.
Remember: The surcharge applies to the package, not the entire shipment.
I just checked at Central Milling, and with a test order, to Indianapolis, it was $14 cheaper, _after shipping_, to order two bags of 25 pounds, than it was for one bag of 50 pounds.
I suspect, and I hope, that many millers who cater to retail customers will start offering 45 pound bags of flour/grain, in order to get a lower price per pound for the flour/grain than a 25-pounder, and which will also avoid the 50 pound package surcharge.
45 pounds allows for a few pounds of shipping material, plus possible moisture absorption by both the product and paper/cardboard packaging.
