Shipping structure changes

I am finding that all too often the shipping charges are costing more than they used to. I am having to make some adjustments to my shipping menu, which means adding a couple of new options for folks as well as adding a couple of dollars to some. I haven't increased shipping prices in a couple of years and in the last year prices have gone up considerably. I am only making slight adjustments to a few tiers. I have added a larger box for overnight as well for the adults of those who are purchasing more than 2 or 3 babies. This will give you more options. Thanks! Shawn
