How do you buy stamps for wedding invitations in the UK?

The most straightforward way is to visit your local post office and ask for the stamps that match the size and weight of your invitations. You can also buy stamps online from Royal Mail's website, which is handy if you are sending many invitations and want them delivered to your door. Supermarkets, newsagents and some convenience stores sell stamps too, but their range may be limited to standard first and second class. If you are buying a large quantity, check whether Royal Mail offers a discount for bulk purchases, but note that prices can change, so always confirm the current rate on the day. For peace of mind, take your fully assembled invitations to the post office counter and ask them to weigh one and confirm the correct postage. You can then buy the exact number of stamps. If you prefer not to queue, you can print postage online using a service that lets you pay and print a label, but that usually requires a printer and adhesive labels. Remember that stamps do not expire, so you can buy them in advance, but the price of a stamp may rise, so buy the right value for the current rate.
