BioTRUST sends coupons to its customers via email and also posts coupon codes to its Facebook page as of 2015. Online coupon websites also provide coupon codes, but the codes may be less reliable or outdated.
The BioTRUST Facebook page lists sales and coupon codes for its website and posts multiple times a day as of 2015. Additionally, if a customer provides an email on the BioTRUST website, the company sends the customer coupon codes via email for free. Online coupon websites such as Promopro.com and Couponfollow.com list sales and coupons, but these are not verified by BioTRUST and may be expired or invalid.
