Anyhow, I wrote a very curt email to the company about their lack of c/s. I received a very nice email back from the VP at Apramo. He says the booster is good for TEN years
"Sorry for late reply. This Alley, vice president of Apramo Child Care Manufacturing Co., Ltd.
Thanks for choosing Apramo booster for your children, all of Apramo boosters are produced under CMVSS 213.2 regulation. Regarding the expire date, we recommend people not to use it 10 years after the manufacturing date.
BTW, 1-866 phone number belongs to Canadian Tire Corportation. I will contact Canadian Tire Corporation to give your the answer about phone number issue.
Any further questions, please feel free to contact me.
Thanks & best regards,
Alley Sun
Vice President"
In fact, he did contact CT and they responded as well. This is what they confirmed:
"Your email inquiry was forwarded to our office by the vendor. Canadian Tire's Corporate Customer Relations is the correct department to correspond with.
The Apramo low back/no back boosters can hold its service life about 10 years.
If you have any questions, please contact our Customer Relations department at 1-800-387-8803, 8:00am to 9:00pm (EST) Monday to Friday and 9:00am to 5:00pm (EST) Saturday.

So there you go. A little frustrating getting the information out of them but they say it's good for 10 years. That makes it a much better price point (especially on sale) than the Walmart Harmony LBB.
