A greeting card is an illustrated piece of card stock or high quality paper featuring an expression of friendship or other sentiment. Although greeting cards are usually given on special occasions such as birthdays, Christmas or other holidays, such as Halloween, they are also sent to convey thanks or express other feelings (such as to get well from illness). Greeting cards, usually packaged with an envelope, come in a variety of styles. There are both mass-produced as well as handmade versions that are distributed by hundreds of companies large and small. While typically inexpensive, more elaborate cards with die-cuts or glued-on decorations may be more expensive.
These are greeting cards for the budget conscious. There are two common formats for reusable cards. Firstly, there are cards with slits in them positioned to hold pages. Secondly, there are notepad style cards where pages stick to the back of the cards. The pages that have been used for reusable cards can be removed after being received and fresh pages can be used to reuse the cards.
