Can you buy pop tarts in singles?

In america you can get all different flavoure...But in the UK...not so much...I would like to try them all, but are not prepared to pay �5 a box plus shipping so was wondering if there was a variety box anywhere that contains a foil pouch of each flavour, or if there is a website that allows you to buy the foil pouches (singles) instead of a whole box. Thanks in advance for you help :D
