Take, for instance, a brand-new Facebook promotion to "Get $4 Off Your Gift" of $5 or more.
The sale pricing is being shown to select members alongside birthday notifications in the right-hand column of the site. A spokesperson for the social network confirmed to CNET that the discounted Gifts offer is a "new test," but would not share additional details.
CNET reporter Shara Tibken first spotted the up-to-80-percent-off message this morning as she was posting a happy-birthday message to a friend's Facebook wall.
Desperate though the ploy may be, it could work. Facebook's store includes a few $5 gift items, which means members can use the offer to send a decent gift, say a $5 gift card to Starbucks, for just a buck. In the process, Facebook gets to keep the member's credit card information on hand, and ideally will be able to convert the one-time buyer into a more regular customer.
