I've had to RMA 2 TFTs this year due to something being loose inside the monitor and making them do funny things (different models and different problems). The first was DOA, the second took a while to show, but I'm convinced both problems were from the monitors being thrown around by Amtrak.
My local depot is outside the city and only open until 6pm, so I have to drive in the traffic leaving town during rush hour since my driver always gets back in at 5 and ALWAYS misses me. Very rarely do they answer the phone either, and I just get told to come along when he gets back or they will re-card me the next day.
Amtrak will also only give 2 days before they return parcels to the sender.
I've never dealt with Citylink in Edinburgh before, but their office is round the corner from where I work.
Whoever mentioned RM as a single option, I would definately never order from ocuk again. In a year I've had at least 4 not recieved parcels from retaillers using 1st class, recorded and special delivery.
