Under the Sale of Goods Act, 1930, where seller delivers larger quantity than contracted, buyer may:

Section 37(2) provides that where the seller delivers more than he contracted to sell, the buyer "may accept the goods included in the contract and reject the rest, or he may reject the whole", and if he accepts the whole he "shall pay for them at the contract rate". He is not limited to rejecting the excess, and accepting the whole carries no discount.
