We've been seeing the same challenges. One product we've consistently had good results with is NexGard Combo. We use it here at PBHSN on both our shelter animals and in our public-facing clinic, and it has continued to perform really well for us.
It's been effective at keeping our population flea-free, and because it's a combination product, it helps simplify care for both staff and pet owners. Given your concern about cost, it may also be worth exploring whether the manufacturer offers nonprofit or bulk-purchase pricing.
