the quote is returned in the HBShopping_USPS_Quote variable:
["HBShopping_USPS_Quote"]=>
float(13.71)
it looks to me like you have the sipping set to One Package for each item ordered, from the cart info, it looks like you have 3 for the quantity of the The Co-Creators Handbook:
4.57 X 3 = 13.71
which is the value stored in the quote.
13.71 + 150 = 15.21
Perhaps you want to ship all items in the same package?
