Man that primer really did disappear from everywhere but I think it's due to it being repackaged so it may return.
I've noticed all the inexpensive primers I like are gone- Essence, NYX, etc. I hope they all return :(
The most inexpensive that I like is the Profusion and they sell it @ Amazon:
Amazon still has the NYX HD eye primer, I heard good thing about the Colorstay Revlon one: https://www.amazon.com/Eyeshadow-ColorStay-Longwearing-Non-Drying-Universal/dp/B075KCVHV1/ref=sr_1_6?crid=2N2AZIW8ZX5P9&keywords=eyeshadow+primer&qid=1648780275&sprefix=eyeshadow+primer%2Caps%2C129&sr=8-6
