The Thomas Scientific Bonus Item Program is a rebate program. Every time you purchase a Bonus Item, you will be earning a 5% credit back to your account. A Bonus Item also saves you money at time of purchase! All bonus items are discounted from their standard list price.

You do not need to sign up for this program. The only requirement is having an active account number, that is in good standing at time of purchase and at time of rebate. As you shop at, look for the Bonus Item ribbon on select products. But don’t wait too long... what is a Bonus Item today, might not be a Bonus Item the next time you shop! So be sure to grab those products right away!
