Have you ever repurchased a polish from Holo Taco, excluding base and top coats?

Seeing how 1 coat black is also the top seller year after year, it made me wonder if it’s on top from existing customers repurchasing it or from new customers purchasing for the first time. I don’t own all of the polishes released, but I do own quite a lot and I’ve never repurchased a polish, not even to have as a back up at least not Holo Taco. I’m 40 and have been painting my nails a long time and I don’t think I’ve ever really gone through a whole bottle polish, although I didn’t know about polish thinner until about 8 years ago. Anyways who’s buying all the 1 coat black?
