Greeting card businesses sell cards designed for people to send or give on occasions such as birthdays, anniversaries, weddings, births, religious festivals and seasonal celebrations. They may also stock cards for everyday messages, including thank-you notes, congratulations, sympathy and get-well wishes. Designs range from traditional and humorous to contemporary, with choices of wording, artwork, size, finish and format. Cards are commonly supplied with envelopes and may be sold individually or in multipacks. Some businesses create and print their own designs, while others retail cards produced by publishers and independent makers. Customers may also find postcards, gift wrap, gift bags, tags, stationery and small gifts alongside cards. Personalised options can include adding a name, message, photograph or chosen design, although the level of customisation varies.
