I was buying a Kingston 4 GB microSDHC Class 4 Flash Memory Card SDC4/4GB from amazon.com, which seemed a good deal at $8.99 with zero-marginal-cost-shipping (Amazon prime, cough), when I noticed something pretty funny.
It seems Amazon also offers the same product in “Amazon Frustration-Free™ Packaging,” for just $10.56 — only $1.57 extra.
Pay more, get less packaging — something you can actually open. I guess it's a business model.
