It depends on how well आप know the couple getting married, and how much आप can afford. My niece got married last spring, so we were very generous with her. आप can see if the couple is registered anywhere; most people do that, and there is usually a range of gift items and prices. आप can also go in with a group of फ्रेंड्स to get a और expensive gift. But at the end, it is your budget, and your फ्रेंड्स do not want आप to break your account for a gift.
