I would have to agree about the Holiday store. Lundeen’s is a great place to get bait. Very helpful on where to go as well. Prince bait on 169 is also very good. Not sure if you go that way or not.
The Jumbos are starting to get smaller as the summer wears on. But Pat’s Bait(27 & 47 in Isle >> The old Ozzies) has had some dandy Jumbos so far this year.
On the west side Tutt’s in Garrison can be good. Can’t vouch for their monster jumbos this year but in the past they’ve had dandies well into the fall.
