Sorry, I realized we described this promotion in our email announcement on Sunday, February 5th. But we didn't give the complete instructions to anyone who might be coming to the site without having seen the email first.
Here's how you can get a free 4 CD set (sorry it's not ANY four CDs of your choosing).
1. If you put 2 items from our very popular 10 CD set library in your cart, add a 4 CD set from our Classical and Jazz 4 CD set collection, which you can access by clicking here: https://www.classicselectworld.com/collections/classical-and-jazz-4-cd-sets
2. The 4 CD set will be shown as free if you've also got 2 boxed sets from our 10 CD library included.
3. And yes, you can get one set for every 2 boxed sets you buy - so, for example, if you buy 6 10 CD boxes, you can get 3 4 CD boxed sets.
