[POUNDS] => Array (

)
[RATE] => Array (

)
)
)
Array (
[0] => price Object (
[mailservice] => Priority Mail<sup>®</sup> Medium Flat Rate Box

...yeah. I need to search through these and pull out the RATE value, which here is 11.35.
For/each loops have failed me so far, any other ideas?

Here is a function to do this for you:
findKey($myarray,$searchKey) {
foreach($myarray as $key=>$value) {
if($key==$searchKey) return $value;
if(is_array($value) || is_object($value)) {
$returned = findKey($value,$searchKey);
if($returned) return $returned;
}
}
return false;
}
// call it like this:
findKey($yourArray,"rate")
