NO. Consolidated has not tendered delivery.
Tender of delivery means that the seller offers the goods to the buyer by putting or holding them at the disposition of the buyer. Seller also gives the buyer some notification reasonably necessary for taking delivery.
In this case, Oscar is open 6 am to 8 pm daily. Delivery arrived at 10 pm where no one is there to accept the delivery. Only until Oscar or anybody that is authorized by Oscar to accept delivery is actually in the premises to receive the goods being delivery will Consolidated be able to tender delivery.
