Jason,
Ok that worked it is now returning a quote for Priority Flat Rate box. The quote returned however is for a Small Flat Rate box even though the Large Flat Rate is specified in the code. It seems to be ignoring the ["PackageType"]= "LG FLAT RATE BOX";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageType"] = "LG FLAT RATE BOX";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageSize"] = "Regular";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageMachinable"] = "true";
$Shipping_PackageArray[$Shipping_PackageIndex]["IPackageType"] = "Package";
It also appears weight is affecting the price returned even though its a LG FLAT RATE BOX.
One magazine weighing 5.6oz. in cart large flat envelope is $2.03 - same as USPS website
Two magazines weighing 11.2oz.is $3.08 - same as USPS website
Three magazines weighing 16.8oz triggers Priority mail. Large box specified. Price is for Small box. $5.80
Six magazines weighing 33.6oz returns a new price of $6.50
We'd actually like it to use a Medium Flat Rate box if you could tell me what the "PackageType" should be.
