Is it good that i added 3 UK 1st class large stamps to an A5 enveloppe to get a response from the UK?
or did i make a mistake. I also have UK 1st Class stamps but 'Large' isnt on there
Please help, im afraid i made a mistake

i think that is abit to much
normally if i'm sending something to europe c5 envelope size i pay about £1.50/1.60
