I really appreciate the opportunity to buy many good products in bundles. But comes a time when due to budget restrictions or preference I just want to buy books individually. However sometimes Logos makes this option inaccessible to faithful customers. I know that some of this bundles or collection are not done by them (I still think they can negotiate that, after all, there is no other place where you are obliged to buy electronic bundles but logos) nonetheless some of them are develop by logos. Finally, I am just begging that you keep the bundles but also offer the option to buy individual resources.
