Seller's Specific Output Claim
Wade Watson purchased a generator from Winslow Aviation after the seller stated in writing that the unit would produce 5000 watts continuously. The generator delivered only 3500 watts during normal operation. Wade sued for breach because the written statement formed part of the basis of the bargain and the goods failed to conform.
Brochure Performance Specs
Winston Ward bought industrial fans from Windham Technologies after reviewing a sales brochure that listed a maximum airflow of 1200 cubic feet per minute. Actual testing showed the fans reached only 900 cubic feet per minute under standard conditions. Winston claimed the written description created an obligation that the goods match the listed capacity.

Sample Model Conformity
Wesley Wong selected a batch of fabric from Winterhaven Logistics after examining a provided sample swatch that showed a tight weave and specific color. The delivered rolls contained loose threads and mismatched dye. Wesley asserted that the sample formed part of the bargain and required the entire shipment to match it.
Informal Written Assurance
Whitney White received an email from Wellesley Media confirming that a purchased printer would handle 500 pages per hour without jamming. The printer jammed after 200 pages. Whitney relied on the email statement even though it used no formal warranty language.
Attempted Disclaimer Conflict
Wyatt Wilson bought a conveyor system under a written contract that included a performance specification. A later clause tried to disclaim all warranties. The system failed to meet the specified speed. Wyatt argued the disclaimer could not override the written assurance because the two provisions could not reasonably be read together.
Manufacturer Written Promise
Wendy Wu purchased a new vehicle from a dealer after reviewing the manufacturer's written booklet that promised the transmission would last 100000 miles under normal use. The transmission failed at 40000 miles. Wendy sought recovery under the written assurance that accompanied the sale.
How does a written statement become part of the basis of the bargain?+
A written affirmation or description creates an express warranty when the buyer receives it before or during the sale and the statement relates to the goods. The buyer need not prove subjective reliance if the statement was made in connection with the transaction.
Supporting sources
Does formal language such as 'warrant' or 'guarantee' need to appear in writing?+
No formal words are required. Any written affirmation of fact or description that becomes part of the basis of the bargain creates the warranty even if the seller had no specific intention to warrant.
Supporting sources
Can a later written disclaimer negate an earlier written warranty?+
A disclaimer is inoperative to the extent it cannot reasonably be construed as consistent with the written warranty. Courts construe the provisions together when possible and disregard the disclaimer where inconsistency exists.
Supporting sources
Does a written sample or model create the same obligation as a written description?+
Yes. A sample or model made part of the basis of the bargain creates an express warranty that the whole of the goods will conform to the sample or model.
