- First a mistake! I wrote that prices increased in 20p increments. As
- Colin Singleton has pointed out to me, this is not so. I don't know
- how I made the mistake but it was when I edited a version which said
- something like "10p and 20p increments up to 77p". Colin also asks for
- clarification about what I mean by 'best' pointing out that using
- nothing but 1p stamps will minimise the value of the stock! As Colin
- surmised, that certainly wasn't the answer I wanted.
-
- I've also received a program in BASIC from Ivor D T Cook for UK postage
- stamps. Ivor is an ex Post Master and says, "I can vouch for the
- difficulties which stamp selection can create, especially when
- customers are waiting at the counter"! Ivor's program uses current
- stamp values and the result of his algorithm is that no more than two
- stamps are used for weights up to 400g and never more than three stamps
- for (almost) any weight. His program called [Postage] is on the
- monthly disc.
-
- Using his program for a typical week of our post I find that, for UK
- use, I am used only the following stamp values: 6p, 19p, 25p, 29p, 36p,
- 38p, 41p, 50p! Further investigation of Ivor's program reveals that
- all 1st and 2nd class values up to 400g can be realised with a
- selection of no more than two stamps from those eight stamp values.
-
- The 'basic solution' of Ivor is the sort of thing I had in mind and,
- although I can't speak for Danny Fagandini, I suspect that such a
- selection is close to the answer to his question. My 'instinct', which
- was to buy 10p and 20p stamps, seems to be based on nothing more than a
- wish to make the sums easy!
-
- What we need now is a spreadsheet solution and a similar program for
- overseas mail. Our two most popular overseas values are 42p and 54p
- which I now make up with 36p + 6p = 42p and 29p + 25p = 54p. For now,
- our next purchases of stamps will be the above eight values and I'll
- make up the overseas postage 'by hand' until someone comes up with an
- Archimedes solution. Does anyone feel able to help?
