On a related note, anti-terrorism measures have made sending food more complicated. Rather oddly, you don't have to register home-made produce with Customs ( which surely is easier to tamper with) but you do all purchased products. The unit of measurement drop-down is unbelievable. It includes such common units as 'tea-chest and barrel'. You have to identify the method of preservation ( irradiation, heat, heat/irradiation) and find the appropriate shape for bottles ( try to categorise Marmite). I gave up and lied that I'd sent the package.
