Hopefully not a basic question. Just getting back into it all. Stopped playing after Pearl. Have a binder full of base set in some box somewhere.

My logic is clear in terms of sealed - buy at mrsp if I can and save some open some.

My logic is less clear for singles/slabs. Why buy most singles/slabs post ~2017 when the psa9 or 10 populations are so high? Is it not wiser going for earlier cards, especially when considering ungraded, psa, and populations. Or am I missing something.
