Hello!  I hope your day is going well for you.  I see you have 2 bag minimum.  If I wanted to buy 50 8lb bags of the microcrystal litter, how much would that cost USD and can you shop it to me (obviously I would pay for the cost) or does it go strictly to port & I am responsible for it from there? I am in Mesa, AZ 85215.   Thank you, Jenny Schuster
