Although prone to parsimony, I also deserve a treat now and then. Having just plastered an awkward stairway wall in a somewhat rustic fashion (the kids are out; they don't need to hear that kind of language), I've sat me down and savoured some Co-op freshly-squeezed Oranj. Lovely it was, and well worth the extra.
What little luxuries make all the difference to you for under a tenner?
...Oh, go on then - spend a bit more if you must.
