Sending Christmas certificates along with cash or a gift both have their significance. However, particular emotions get attached to the gift if it is sent to your close ones, and your thought will come to their mind every time they use the thing given to them as a gift by you. On the other hand, some people prefer to give cash amount because of their busy routines due to which they could not find enough time for buying a gift. The cash amount can also be given in a sense if you do not know other people's preferences, and they will buy anything they want from that cash amount you give. You can decide the amount of cash given depending on your income and budget.
