Given that Taylor and Jamie verbally agreed to add the wireless feature at an extra cost, but no written amendment was made, can MRU dispute the additional $7,500 included in the invoice? The agreement for them to add the wireless feature at an extra cost of $7500 can be seen as a gratuitous promise, due to the fact that there was no written amendment or additional considerations. Hence allowing MRU to dispute the $7500 charge on the information that the alteration is unenforceable unless there is fresh consideration, the preexisting legal duty showed that there was nothing written about a addition to a wireless remotecontrol feature so under the contract they are not required to pay the additional $7500. Moreover, according to section 6 of the purchase order terms and conditions, any price that increases or additiona; charges must be agreed to in writing by the University to be effective.
