There's more, too, that offer similar services if you Google. I used thecpediscountstore.com and wasn't impressed with them, but I think they changed ownership or something like that midway through the time I was using them, because they did seem to improve slightly, so might be better now. However, my experience with them was not positive.
I would suggest looking at the courses offered through all of these unlimited providers and find one that offers courses that interest you. Do you want to learn about retirement plans, about non-profit accounting, or about fraud auditing? Of course some of your CPE requirements are set in stone (at least in most states – x hours of ethics, etc.), but some are “electives”, so find a provider that offers courses that look interesting to you, then go with them.
When I did my CPE through CPEDiscountStore, I was interested in learning more about retirement plans for personal benefit, and I had also fairly recently started a job in a non-profit, so I took CPEs related to retirement and non-profit accounting for all the “electives” that I had. Given that my state does CPE on an every-2-years basis, that was quite a few electives. 😛 However, I enjoyed the CPE more since it was topics that interested me, instead of “Oh, I get to study FAR again, 1 CPE hour at a time…”
P. S. Especially for the online/self-study methods, I preferred courses that were many credit hours to courses that were a few, so you might want to look for someone that offers larger courses. CPEDiscountStore seemed to basically have x many questions on the exam for each credit hour of materials provided, so a 16-CPE-credit course had an exam 16x as long as a 1-CPE-credit course. I preferred to spend 16 hours studying 1 set of materials than to spend 1 hour on one topic than 1 hour on another etc. Don't know if you'll be the same, but might want to at least find a provider with variety of course sizes so that you can try both approaches.
