They are classics being retired to make room for newer formulas, which is why they are discounted rather than reformulated. If one of them is a staple for you, now is the point at which to buy more than one.

Mineral Pressed Base and Voila Finishing Loose Powder are the two most people use daily, so they empty fastest. Beach Glow Bronzer lasts a long while from one compact, and Repair Lip Therapy is worth doubling if you like the tint.

The color range keeps evolving, so newer options cover similar ground, though a discontinued shade or finish will not return in the same form. If a specific finish matters to you, buying now is the safer approach.

Powders keep considerably longer than creams, often a year or two if kept dry and closed. That is what makes stocking up on a pressed base or a loose powder sensible in a way it would not be for a liquid formula.
