If it is cheaper in this place, that is still called Leka Darka Achrina. Remember, it doesn’t have to be Oness. The point is that you are there, and you know you there, for a purpose.
If indeed, there is another choice, just as good, then this Hetter wouldn’t apply. However, instinctively I think that a Rov would be Mattir based on everything else brought up here by others and myself.
