We have to use a parcels agent for international (or Hermes to places like NI, the IofW or NW Scotland) because we do not spend enough to be able to deal with more than one carrier (plus the RM) directly. In fact when we dealt with TNT (who also ship internationally) it was still cheaper to use ParcelsToGo than TNT despite the fact we were spending about £3K a month with TNT back then. Sometimes it was even cheaper to book the same TNT service through ParcelsToGo than book them direct ! That was quite annoying..... ParcelsToGo [sic] are pretty good (they are cheap and I like their monthly invoice statements which list the VAT separately), until something goes wrong. Then it's a nightmare...... But, as I said earlier, it very rarely ever used to go wrong.
