Buy in bulk. Price is a lot cheaper. Grow my own herbs. You can dry them for the winter, if necessary, or bring them in the house.
Make my own vanilla extract, which involves a bottle of vodka and some vanilla beans that have been opened. 1 cup of non-flavored vodka and 5-6 vanilla beans. (I buy them online.) Place in a tight closing container and leave it alone for 6 months. A fifth of vodka can make several batches of vanilla extract. You can also use bourbon, rum, or brandy. Also makes for a great holiday gift.
