Merz67 via eBay offers the Wacom Bamboo Expandable Stylus Pen for iPad and iPhone 3-Pack, model no. CS200S, for $4.75 plus $3.25 for shipping. That's $2.67 per stylus and the lowest total price we could find for this quantity by $4, although we saw a 3-pack for a buck less in December. Each stylus is compatible with a range of tablets and eReaders, featuring a 6mm tip and collapsible barrel.
