Hi all! Has anyone here used PAL Cargo Services before?

I am flying with PAL with just 20kgs allowance for checked-in baggage. Excess baggage fee is ridiculously expensive! They don't offer pre-paid baggage services either - only for local flights! So we found this PAL Cargo Service in their website.

If you have any knowledge or experience with this service, please let me know if it was worth it or not?

Thank you.
