We show that for any finite set $P$ of points in the plane and $ε>0$ there exist $\displaystyle O\left(\frac{1}{ε^{3/2+γ}}\right)$ points in ${\mathbb{R}}^2$, for arbitrary small $γ>0$, that pierce every convex set $K$ with $|K\cap P|\geq ε|P|$. This is the first improvement of the bound of $\displaystyle O\left(\frac{1}{ε^2}\right)$ that was obtained in 1992 by Alon, Bárány, Füredi and Kleitman for general point sets in the plane.
