Umi Grill has ordered from “Fish R Us” for the last eight (8) years. Due to Covid-19, Fish R Us has found it difficult to obtain all the fish it previously had. Therefore, Fish R Us had to raise its prices. Umi Grill ordered their shipment of fish and received the order from Fish R Us. Fish R Us placed a note in the box advising that they had to raise their fish prices and if Umi used the fish, they were accepting the $150.00 increase. Umi Grill used the Fish for meal preparation. Would Umi Grill be successful in arguing that they did not accept Fish R Us’s new Offer of the increased cost of $150.00?

a. Yes, because there was not a valid offer.

b. Yes, because silence by acceptance is not appropriate acceptance

c. No, because it is illegal to change the price

d. No, because silence by acceptance can be appropriate since they had been dealing with each other for eight (8) years
