As far as combining unrelated services goes, a pharmacy-slash-post-shop is a pretty good mix. The downside here is only that, this being a less than massive shop, you don’t get a huge range of either service, or at least not as much as you would in a larger place — or one that didn’t have its attention divided. But this is probably not really an issue. Certainly the few times I’ve been here they were able to sort me out with whatever I needed, so they have at least the more obvious range of both a pharmacy and a post shop(I’ve never gone in asking for anything obscure or weird, so I can’t say how they’d deal with less common requests). The service here has always been polite and professional, and although I have had to wait in line, it’s never been for very long.
