I am in the same boat:
purchased 3 cases of Pergo Presto Golden Chester Oak Blocked PH 4591 at Home Depot.
I procrastinated and now I need 4 more cases to finish the project, but the product is discontinued.
I called Pergo and verified that PH 4591 is NOT compatible with the new "Golden Chester Oak" (PH 4711) which is currently being sold.
I'd be willing to sell my 3 cases to you.
