Solution 10550: Determining Expiration Dates for Proof of Purchase Labels (POPs) or Points.
Do proof of purchase (POPs) labels or points have an expiration date?
Proof of purchase certificates that state 10 Level 1, 10 Level 2, 10 Graphing, and 1 (graphing) as well as UPC barcodes used to redeem rewards in the TI Technology Rewards Program will no longer be accepted after December 2010.
Points do not have an expiration date. Educators may use points from any combination of the products to receive rewards.
