Went to Kobey's in San Diego yesterday and scored some nice finds. Probably too late by the time you get this message, but there's a guy with a little box of Snowbank Jack's $5 chips, way out to the northwest in the Clothing Items aisles, across the river. (I bought a few some months back & don't need the remainder of his stock.)
For those who don't know the Rose Bowl layout, yes, a river runs through it. But they have a couple of bridges so you don't have to get your toes wet.
Good luck, Fred, there's almost always some interesting stuff offered though you'll have to look hard to find the casino-related items all the other wares.
