Anointing oil for sale, tabernacle incense, and a mailed communion sampler

The conversation moves from the highway story to the commercialization of religious practice: whether anointing oil can simply be bought at a Christian bookstore, what substances count as anointing oil, and whether the tabernacle's holy incense (the recipe given to Moses, with some ingredients withheld) could even be made today. A host recounts receiving an all-in-one sealed communion cup-and-wafer sample in the mail from a sound-equipment vendor, the vendor's pitch about freshness, and his own full communion taken at home from the sample.
