Over the years, I've become a big fan of buying used goods. I'm on eBay, on Marktplaats (a Dutch subsidiary of eBay), I like jumble sales, car boot sales, 'kringloopcentra' ('recycling centres', it's what the Dutch call used goods stores with or without a charitable purpose) and charity shops. When I need or want something that I don't necessarily feel I have to buy with a warranty, I'll buy it used if I can.
Much of the photographic kit I used when I was still using Canon, was bought on eBay. And when I decided to sell it so I could buy my new Olympus, I sold it on Marktplaats. (And actually made a profit on a few items, not bad.)
I haven't found any good photographic buys on jumble or boot sales yet, or in charity shops. But charity shops are great for buying clothes, I found.
Take this Daks jacket, for instance. Immaculate condition, but only a tenner. The shirt was two pounds from another charity shop, the tie was new. Altogether I spent two tenners on this 'look'. Not bad!
(I suppose with that thought, I should have looked happier in the photo, but I was concentrating hard on positioning the iPhone just right for the self-portrait.)
