I'm the kind of guy that does a couple certifications a year. Because of the tech stack I work in, most of these end up being Microsoft certifications. This year I ended up using the MS E-Learning for two SharePoint certifications (MCTS') and it wasn't half bad. Some of the material is a little cheesy and has a touch of marketing propaganda. It's also the kind of material you probably want to supplement with some MearsureUp or Transcender to ensure that you pass your exam the first time.
All that being said it covers the material in a efficient way and highlights a lot of the features of the product that you may not know about. The material could usually do with a little more depth, but it makes you aware enough to go do some research on your own if you want to go deeper. At the very least it helps you pose the right questions to go further your own learning.
The below is from an MS E-Learning promo site:
Official Microsoft E-Learning provides you with a cost-effective, flexible, and easy way to build your skills on Microsoft technologies.

So there you have it, a chance to save yourself (or your employer some money) if you were planning on doing some certs this summer. It's of note that the classes remain available for 18 months and only take about a week to go through so it may be worth signing up now and doing them later.
When I went through there were two promo codes, one for a free e-learning course and another which gave a 20% shopping cart discount.
So there it is, take it as you will.
