The most coveted chips did sell out in minutes. I couldn’t get any 2.50s literally one minute after they became available.
There’s more 1s 5s and 25s than you probably think.
10s of thousands of 1s and 5s etc. similar sales had 40-50k $1 chips!
When I built my HSI set, I got the good stuff early first minute. then a couple months later, Jim made the 1s discounted because there were still so many left. I bought an additional 1000 $1 chips for like .60c each. But the rest of my set, sec. 5s sec. 25s, pri100s 500s all sold out within minutes. Glad I nabbed them.
You never really know how many of each there are, so you kinda got to do all the main parts of the set first day, or else you will miss out.
