How long do you give your guy to respond before you try to find someone else?

I had a great dealer who had excellent stuff from Cali I believe. Great selection with high quality Notmally he would reply in a few hours and now he hasn't texted me back in few days. I have been going thru him for a while and it seems like he just disappeared. I got so use to those awesome 710 King oil pens and am hoping he responds soon. Plus he was out in the western burbs making it so easy. How long do you all wait before you start thinking your connection is done? 😞 so bummed!!!
