Are Gifts for Sale?
When one receives a gift, they may sometimes wish to re-gift the item or sell it. However, if the giver expressly stipulates that they do not want the gift to be passed on, or that they wish for the recipient to use it themselves, the recipient may not re-gift the item or sell it. Generally, if there is an inscription on a gift, it’s an indication that the giver wishes the recipient to keep it. In the case of a wedding or a Bar Mitzvah gift, however, inscriptions are customary, and usually not an indication that the giver does not want their gift to be passed on.
If one wishes to give a present to a parent—and because it’s a very special, chashuve (important), expensive, or valuable gift—they would like to stipulate that after the parent leaves this world, they should be the one to receive the gift as part of the yerushah (inheritance), they may do so. However, if they prefer not to discuss it with their parents directly; there is a halachic procedure to follow for arranging this, and one should consult a rav for the proper manner in which to do it. 385
