(1) Unless otherwise agreed tender of payment is a condition to the

seller's duty to tender and complete any delivery.

(2) Tender of payment is sufficient when made by any means or in any

manner current in the ordinary course of business unless the seller

demands payment in legal tender and gives any extension of time

reasonably necessary to procure it.

instrument on an obligation (Section 3--802), payment by check is

conditional and is defeated as between the parties by dishonor of the
