I think merchants or businesses like making money off of pretty much anything can make a huge profit off of. That includes the Birth of Jesus because is that not the time of year stores have the most profits?

The merchants, as do the Men of God who pass the plate, will take the money and use it for many useful and noble purposes.

Of course the commercial entities enjoy making money of the supposed birth date of Jesus. They have to do this now because the Bible has prophecied that this profit will dry up in the future by what is recorded at Revelation 18: 1-19 After these things I saw another angel descending from heaven, with great authority; and the earth was lighted up from his glory. 2 And he cried out with a strong voice, saying: “She has fallen! Babylon the Great has fallen, and she has become a dwelling place of demons and a lurking place of every unclean exhalation and a lurking place of every unclean and hated bird! 3 For because of the wine of the anger of her fornication all the nations have fallen [victim], and the kings of the earth committed fornication with her, and the traveling merchants of the earth became rich due to the power of her shameless luxury.” 11 “Also, the traveling merchants of the earth are weeping and mourning over her, because there is no one to buy their full stock anymore, 12 a full stock of gold and silver and precious stone and pearls and fine linen and purple and silk and scarlet; and everything in scented wood and every sort of ivory object and every sort of object out of most precious wood and of copper and of iron and of marble; 13 also cinnamon and Indian spice and incense and perfumed oil and frankincense and wine and olive oil and fine flour and wheat and cattle and sheep, and horses and coaches and slaves and human souls. 14 Yes, the fine fruit that your soul desired has departed from you, and all the dainty things and the gorgeous things have perished from you, and never again will people find them. 15 “The traveling merchants of these things, who became rich from her, will stand at a distance because of [their] fear of her torment and will weep and mourn, 16 saying, ‘Too bad, too bad—the great city, clothed with fine linen and purple and scarlet, and richly adorned with gold ornament and precious stone and pearl, 17 because in one hour such great riches have been devastated!’ “And every ship captain and every man that voyages anywhere, and sailors and all those who make a living by the sea, stood at a distance 18 and cried out as they looked at the smoke from the burning of her and said, ‘What city is like the great city?’ 19 And they threw dust upon their heads and cried out, weeping and mourning, and said, ‘Too bad, too bad—the great city, in which all those having boats at sea became rich by reason of her costliness, because in one hour she has been devastated!’
