Are the free CEUs the ones offered by IDEA for signing up or renewing a membership with them?
If so, I had a similar issue several months ago. I clicked on a link provided by IDEA for free CEUs but then tried to search beyond the options immediately presented to me. This was a mistake. After lots of searching I ended up just choosing one of the options listed on the page the original link routed me to. I went through the “checkout” process and, in the end, the price was adjusted to $0.
I hope this helps. If not, I’d recommend you give them a quick call at 1-800-999-4332 or try to Live Chat with them when a representative is available online.
