A couple of months ago Flyertalk member AndyAndy reported that the offer of 2500 Priority Club points for an AT&T Wireless purchase could be used for a refurbished Nokia 2610s which runs $25 and includes a $25 airtime card.
Now, I wouldn’t spend $25 for 2500 Priority Club points unless my only use for those points was PointBreaks (where 5000 points can be redeemed for a free night), then it’s worthwhile. Otherwise I value Priority Club points at around 2/3rds of a cent apiece.
However, since you can sell the phone on eBay even without the airtime for close to the purchase price, for those willing to go through the machinations this could be a great deal to generate more or less free points and free airtime. (Some will use different sim cards with the same phone and not be considered about a phone number change even because they use a GrandCentral phone number that’ll forward to whatever number they’re currently using, but that’s way more complicated than most will ever care to get.)
This is especially useful since AndyAndy has confirmed in the thread that you can earn the 2500 Priority Club points multiple times, and for him the points posted without any followup required.
