Regarding the other part of the whole thing - the who you book through. Don't use Interparcel unless you're prepared to just accept whatever goes. I had two parcels "delivered" by UPS within two days of each other. I use the term "delivered" loosely because instead of delivering them to my door the UPS guy took it upon himself to just drop them off at the local drop-off point.
Now I'll admit that wasn't much of a hardship, the drop-off point is the corner shop at the bottom of my road, but I only found out AFTER we'd stayed in all day and then on checking I happened to notice the parcel had been delivered. Fortunately I recognised the name of the person that works in the corner shop.
So anyway, so far nothing to do with InterParcel. One of these was out of my control, it was ordered by the sender, the other one however I ordered and supplied the sellers address as the pickup, mine as the delivery. And there's a £2.80 difference between delivery to my door or the corner shop so I registered my request for a refund on the difference. Long story short, after a couple of weeks of being fobbed off by someone at IP all responses eventually stopped and they have been added to my list of people never to do business with.
f**king joke that they seem to think that it's acceptable to deliver when and where they feel like, yet happily charge you for a specific service and timescale!
