Amazon
+ 16GB Sandisk Extreme SDHC (45MB/sec) for $19. You can buy as many as you like at this price

+ these ship in "frustration free packaging" which is typically more environmentally friendly than retail packaging (obviously I don't know how these orders will be packaged since it depends on many factors, but some of the frustration-free packaging items come in sturdy little cardboard boxes that can be reused/repurposed)
+ free shipping for Prime members or if the total of your order is $25+
+ prices can change at any time
