McAdams Company, a TV manufacturer and supplier in Minnesota, received an email offer from Discount TVs, a retailer in New York, stating:

Please send 300 flat screens 32 Smart TVs manufactured by McAdams, to Discount TVs. Deliver to Discount TVs, 1100 Main St, Bluffton, New York by August 1, 2017. E. Smith for Discount TVs.

McAdams replied by email:

We accept your purchase offer and will send 300 TVs to your place of business in Bluffton, New York promptly. L. Martinez for McAdams Company.

McAdams shipped 300 flat screens 36 Smart TVs at a price of $150 each to Discount TVs on August 28.

Upon receipt of the 36 TVs, Discount TVs emailed McAdams Company, stating:

We ordered 32 TVs and received 36 TVs. We cannot use 36 TVs. Your order is incorrect.

At this point, what options does Discount TVs have? What options does McAdams Company have?
