...perfumeorpoison with a very good guess of 502.
I actually have 493 lipglosses. (To those who asked yes, I did count them!) :)
To answer another question, I don't really pay attention to the 6 month expiration rule, I only throw away lipglosses (or make up in general) if they smell or taste bad, or their consistency changes. I did actually chuck out 10 lipglosses the other day, most of them were around 5-6 years old.
Congratulations perfumeorpoison, your prize will be posted to you as soon as possible! Thanks to everyone for taking part, hope you enjoyed it. If you haven't seen the video of my lipgloss collection yet, you can check it out here.
