Post office postal costs???

i posted a DVD boxset in a jiffy bag on special delivery at a small post office branch and it came to 拢5, a couple of days later i posted a letter with tickets in it at a larger branch on special delivery and it came to 拢5.70, i don't get it? the DVD package was heavier, larger but cost less, do larger branches take more money from you to deliver?

i don't think i am mistaken i have the reciepts in my hand, just asking why something lighter cost more than something heavier

I dont think so that it makes a difference on the postage
depending upon the size of the post office.
However there could be other factors involved, like,
sometimes if you use the package supplied by the
post office, the charges are sometimes less,
some kind of packages it is the same charge for the
first half kg, sometimes there could be a promotion on
some kinds of packages, if you check the website of
your local post, you will find most of the details including
the postage on different packages and sizes and weights.
Best wishes.

Special Delivery up to 100g is 拢4.30. Up to 拢500g it's 拢4.75. There is no 拢5.70 level. So you are mistaken.

I repeat - the amounts you paid are not Special Delivery rates. The weight and cost are caculated automatically at the Post Office.

What letters do the receipts being with? They should be something like ZV xxxx xxxxx GB

I have no idea, maybe the scales were wrong.
