SD memory cards - all proven working

5 SD cards from my earlier DSLR days, all tested recently and working. $2 each for the 2 gb cards; $2 for the memory stick duo card compatible with Sony digital video camera; $5 each for the 4 gb and 8gb cards. Open to reasonable offers from good people. Great for early DSLR (D3000 and D5000 or earlier), and for data safety.
