UCC § 2-718
Liquidation or Limitation of Damages; Deposits
(1) Damages for breach by either party may be liquidated in the agreement but only at an amount which is reasonable in the light of the anticipated or actual harm caused by the breach, the difficulties of proof of loss, and the inconvenience or nonfeasibility of otherwise obtaining an adequate remedy. A term fixing unreasonably large liquidated damages is void as a penalty. (2) Where the seller justifiably withholds delivery of goods because of the buyer’s breach, the buyer is entitled to restitution of any amount by which the sum of his payments exceeds (a) the amount to which the seller is entitled by virtue of terms liquidating the seller’s damages in accordance with subsection (1), or (b) in the absence of such terms, twenty per cent of the value of the total performance for which the buyer is obligated under the contract or $500, whichever is smaller. (3) The buyer’s right to restitution under subsection (2) is subject to offset to the extent that the seller establishes (a) a right to recover damages under the provisions of this Article other than subsection (1), and (b) the amount or value of any benefits received by the buyer directly or indirectly by reason of the contract. (4) Where a seller has received payment in goods their reasonable value or the proceeds of their resale shall be treated as payments for the purposes of subsection (2); but if the seller has notice of the buyer’s breach before reselling goods received in part performance, his resale is subject to the conditions laid down in this Article on resale by an aggrieved seller (Section 2-706).
Professor's notes
Elements: (1) damages for breach may be liquidated in the agreement but only at an amount that is reasonable in light of the anticipated or actual harm caused by the breach, the difficulties of proof of loss, and the inconvenience or non-feasibility of otherwise obtaining an adequate remedy. A term fixing unreasonably large liquidated damages is void as a penalty; (2) where the seller justifiably withholds delivery of goods because of buyer's breach, the buyer is entitled to restitution of any amount by which the sum of his payments exceeds the amount to which the seller is entitled by virtue of a liquidated damages clause or 20% of the value of total performance or $500, whichever is smaller.
Common misunderstanding: students miss that § 2-718(1) uses "anticipated OR actual": the disjunction makes UCC liquidated damages easier to uphold than R2d § 356 (which some courts read conjunctively). Subsection (2)'s 20%/$500 floor for buyer's restitution after breach is a consumer-protective default.
