Back in the day postage stamps used to have a value printed on them and you could then check the cost of postage and (if you could do sums) select the correct stamps to make up the required value.
A while back they stopped printing face values so that you could pre-buy loads of stamps and then use them over a period hedged against any price rises.
Then they introduced different charges for different dimensions of letters.
All well and good but the price calculator from the Royal Mail at
It seems to say that for a Letter, 1st Class stamp, you pay £0.67p. However for a Large Letter 1st Class stamp you pay from £1.01.
If we (naively) assume that the entry level Letter means that a 1st Class stamp is worth 67p and a 2nd Class stamp is worth 58p then how do you pay the £1.01 for a Large Letter up to 100 grams?
So does anyone know of an on line resource which can map the number of 1st and 2nd Class stamps onto the required postage?
There are other probably obvious stupidities, such as can you use a mixture of 1st and 2nd Class stamps to make up the postage for a 1st Class letter?
As you can tell, I don't use the Royal Mail very much.
I do, as it happens, have quite a large number of 1st and 2nd Class stamps from various sources.
