Exactly. That's standard practice for Flash, in my personal experience. Every single time.
With Kerry, on the other hand, they always used to deliver it the same day, even if it didn't arrive until lunchtime. Now though, they do things like mark a parcel out for delivery when it isn't, then claim they've lost my address when I phone to find out what's happened. After two similar incidents, I normally just ask sellers to use EMS instead (if Kerry is their regular option). None have refused so far.
