Since I placed my order already, it gives me the following message when I click on that link again.:
"Thanks for your interest in this special offer.
We're sorry, but this offer is limited to once per household, and has already been redeemed. The offer may have been used by you, or someone in your household in a previous order.
The once-per-household rule applies even if you have more than one drugstore.com account. To find out more about the rules for using special offers."
If it's not working, qqh me your email address. I'll forward the email to you.
