Nope, but it depends on the method of delivery they use, which is dependant on the cost.
I think under £150 its standard mail, (not likely to be 'sprung' but takes a few weeks to arrive).
£150-£250 it's reg'd airmail (about a week, and not as likely to ne 'sprung').
£250+ courier only (and likely to be caught I think).
Check the postage section on their website for the exact amounts and clarification.
