The price of elf primer can vary depending on the brand and quality. Generally, you can expect to pay anywhere from $10 to $20 for a bottle of elf primer. However, if you're looking for a high-quality primer that will last you a long time, it may be worth investing in a more expensive option. I've found that the higher-end primers often offer better coverage and a smoother application, so you may want to consider that when making your decision.
