One of the things that struck me when I moved here was how the Post Office do a lot to remain relevant in this email age.
As well as standard services the Post Offices sell all kinds of stationary, cards, sweets, travel accessories (samsomite wallets for water etc), stamps to print your address, books (similar to an airport selection), photo frames and provide digital photo printing. The thing I find most interesting is that in more remote parts of Switzerland the Post Office vans offer public transport - the idea being if the van has to drive up to some hut up the mountain they might as well make money and offer hikers lifts up.
