Another postal service is Fed Ex.

FedEx-a worldwide network of companies providing customers and businesses with the same "absolutely, positively" zeal for service you've come to expect. FedEx is provides strategic direction and consolidated financial reporting for the operating companies that compete collectively under the FedEx name worldwide: FedEx Express, FedEx Ground, FedEx Freight, etc...

If we choose the box of 10 or 25 kg, from Germany to UK, our choices are:

10kg Box 92 Euro Every additional kg 4 kg 25kg Box 137 Euro Every additional kg 6 kg

Conclusion
Last but not the least, we could compare the two postal services DHL and FedEx with the starting point as Germany and the destination as UK. If we have a package of 10 kg or 25g to send to UK, and what kind of decision we should make? We could easily see, that the service of DHL is much cheaper than FedEx. As customer, the postal service of DHL is the best choice. And I will use the information to make a decision table with the software prologa, from this table, we could clearly see what decision we have made.

The next step is to use Prologa to do the decision table. And use this software, we could clearly see how we made a decision and what the result is.
