My custom shipping for Greek Postal Service (EL.TA.)

My store is based in Greece and I wanted to include shipping rates for the Greek postal service (????) so I made this and hope that when someone else needs it in the future they will google it and see this post.

It is basically weight-rate but with predefined values and calculation rules.
If in the future ???? changes it's prices I will update the file. If for some reason I don't, then it's not a big deal figuring out how to do it yourself.

You can grab this shipping rate file ftom here
