Stop buying before card show?

Happy 4th everyone! For the most part I just collect.

Curious on people’s perspective. Do you guys stop buying a couple weeks out, two weeks or doesn’t make a difference? Will buy regardless?

I’ve kind of said in my head to stop within two weeks of a show thinking I’ll regret it if i find a better deal at the show. Then if I can’t find the card or get the deal I want I’ll look more aggressively after the show is done.
