5-6 stamps a week would add up to 250-300 per year. A second class stamp in 2012 cost 50p. Your £60 worth of stamps would have only bought you 120 stamps, enough for 6 months. Two years ago they were probably dearer.
Dodger....I may have been mistaken about exactly what I spent but stamps were most certainly not cheaper when I bought them, .....I can assure you of that !
