I do a lot of
ebay buying for work (yes I'm cheap!). China is cheaper than everyone, and I heard somewhere the Chinese authorities subsidise the postage.
Things like monitor arms are cheaper from Germany than the UK, where a £60 item will be sold at £400. Barcode scanners which have less life expectancy than a WW1 fighter pilot in our factory are £65 from Bulgaria, but £200+ in the UK.
Off on a tangent for a mo, I get all the IT equipment used off ebay. Up to four year old bombproof i5 Dell Optiplex for £99. Dell 22" monitors for £75 (new I think they're a few hundred). Network switches are always new and servers less than a year old. As long as I have a backup regime tighter than a ducks' botty all is good.
Factory scanpoints are £50-£65 for a HP Thin Client that's £250 new. The old shape monitors for those are skip fodder and I pick them up for £10.
IT supply firms take me off their call lists when I tell them about my strategy.
Edit#1 - It's not 'all' cos the switches are new - but hey I type faster than my brain works!
