Is there nothing like Timpsons [1] in the US? Small units in arcades and indoor markets or near railway stations in most UK towns of any size. They do key copying, watch batteries and straps, shoe repairs (where feasible) and, yes, shoe laces.

Stoll's site, the Klein bottle hats and Mobius scarves! "Two manifolds for one low price". I'm after those for autumn.
