One can purchase a string of lights for the holidays from any decent discount store. Alternatively, there are many offerings for sale on Amazon and eBay.

As offerings can only be given when the Temple is standing, no offerings have been made since 70CE. As per the Torah, prayer replaces offerings when we are without the Temple.

We can classify offerings in several different ways: You can classify them by what is offered, so there are offerings of bulls, sheep, goats, grain, unleavened bread, meal, oil, and wine. You can classify them by what happens: There are burnt offerings, where the whole gift goes up as smoke. There are offerings where part is "turned to smoke" and part is eaten by the priests, and wave offerings where the whole thing goes to the priests after being waved before the altar. These can be thought of as a system of taxes on the people to support the priesthood. There are offerings where part goes up in smoke, part goes to the priests, and part goes home with the person who offered it -- for dinner. You can classify offerings by why they are made: There are daily offerings, special Sabbath offerings, festival offerings, peace offereings, offerings of thanksgiving, offerings marking the return of someone to ritual purity, and sin offerings.
