Absolutely, unprofessional. I placed an order on 9/2/21, for discounted items. They guaranteed shipment. After calling twice, I received an email that the item is out of stock and will not be available until 10/10/21. I've placed orders for tge same item in the past and received within 10 days. No one even took the liberty of updating me. Similarly, the same product I ordered is now available for purchase on their website for the original price.
I will be finding another supplier for my business needs.
