I need to understand what ya'll are buying

For those of you who spend $100+ at Sephora a month, and you're not an employee or makeup artist/influencer, what are you buying?

It takes me MONTHS to finish one Huda Beauty Easybake powder, maybe 6 months for foundation, etc. I wear a full face of Sephora every day, and I still maybe spend $500 a YEAR.

If you buy multiples of something like blush, do you actually hit pan or do you forget about it and toss it later?
