A greeting card can cost anything from 50 cents to 10 dollars. The average price of a greeting card falls between the $2 – $4 price band. This is an interesting figure as it shows what the market accepts as a fair price for a card. The Greeting Card Association also report that, "Cards featuring special techniques, intricate designs, and new technologies are at the top of the price scale." This would suggest that handmade cards that feature lots of detail and unique designs should be able to command higher prices.
How much will you pay for a card? Any target price in your mind? To me, it is around $2.
