I bought a MIDI keyboard off Ebay recently. The seller arranged a collection with Royal Mail, which never materialised, so on Tuesday he took it to a post office. 48 hour tracked, so Thursday was a reasonable expectation for its arrival. However, no sign of it, and still no sign today, a week after it was dispatched. Seller has been really good, fortunately. The package was so good that RF received it twice. Maybe they lost it down the back of the settee after the first time, then found it again.
