Abstract: Motivated by ``finite alphabet'' approximation problems in infinite-dimensional Banach spaces we study the behavior of the inhomogeneous minimum of a convex body $K$ with respect to the integral lattice $Z^n$, if $Z^n$ is compressed along (some of) the coordinate axes. In particular, we show that for certain convex bodies and deformations the inhomogeneous minimum can be arbitrarily large which answers a question in the negative posted in the context with the above mentioned approximation problems.
