Later this year I'm likely to be looking to buy 50 or more Micro SD cards with capacity of 128MB (yes, MB not GB) or more. Looking at prices, RS and e14 sell them but don't actually have any quantity dicounts and are more expensive than Officeworks ($8), I was hoping for at least under $5.
I'm not interested in irreputable suppliers likely to be selling Chinese fakes. It doesn't matter how cheap they are if they'll probably all turn out to be duds.
Used cards may be an option, and I've watched a few sellers come and go on Ebay offering mixed lots of cards presumably pulled from old mobile phones. I'm curious whether these people work in phone stores handling trade-ins, or with one of the electronics recycling mobs. I tried to investigate the latter with the hope of being able to do some sort of back-door deal, but they don't seem to give addresses for their sorting centres (actually they seem a bit dodgy, probably unsurprising given the recent scandals in the recycling industry).
Buying off Ebay is still an option of course, I just feel like it might be better getting them from the source. I'll try in some small independent phone shops when I next have spare time in a city large enough to have them, though I'm not really sure how to find them.
So any tips for cheap Micro SD cards new/used of any capacity would be appreciated.
