guage, particularly when read with § 2-709(3)’s implied hierarchy of remedies, to conclude that the drafters also did not intend it to apply when one of the other remedies would put the seller in as good a position as performance would have done. The remedial policy of the entire UCC seeks no more than that. Decker has spoken of the need to “punish” Edison, but the UCC specifically rejects damages which would punish the breaching party except in the most egregious circumstances. § 1-106(1) and comment 1. Decker is entitled to the benefit of its bargain, but not more.
Against all of these considerations, only the ambiguous statement in § 2-703 comment 1 that “the remedies are essentially cumulative in nature” lends any support to the idea that a seller who can get the full benefit of his bargain under § 2-709 can seek even more under § 2-708(2). We do not read that comment as authorizing a windfall. Cf § 1-102(1) and comment 1 (UCC should be construed in accordance with its underlying purposes and policies); Nobs, 616 F.2d at 215; Melby v. Hawkins Pontiac, Inc., 13 Wash.App. 745, 537 P.2d 807, 811 (1975). Decker’s recovery is limited to whatever would be available to it in an action on the price.
With the action properly characterized, the rest of the disputes are easily resolved. Decker gets the contract price under § 2-709(l)(b); under § 2-709(2) Edison, once it has paid the judgment, gets the right (until 1990) to mine the reserve coal. Unlaub Co., Inc. v. Sexton, 568 F.2d 72, 77 n. 5 (8th Cir.1977); Wolpert, 254 N.W.2d at 350; FMI, Inc. v. RMax, Inc., 286 S.C. 343, 333 S.E.2d 360, 362 (S.C.App.1985). In an action for the price, the seller is entitled to its damages from its loss of the use of the money it would have had if the buyer had paid on time — i.e., some level of prejudgment interest — as incidental damages resulting from the breach. §§ 2-709(1), 2-710; Bulk Oil Co. (U.S.A.) Inc. v. Sun Oil Trading Co., 697 F.2d 481, 484-485 (2d Cir.1983); Klockner, Inc. v. Federal Wire Mill Corp., 663 F.2d 1370, 1380 (7th Cir. 1981). We see-no reason not to consider the contract rate of interest as the parties’ liquidation of those damages under § 2-718(1).
The parties, leaving no stone unturned, present one further question: whether post-judgment interest in this diversity case is governed by the new federal interest statute, 28 U.S.C. § 1961, or by the Illinois statutory rate of interest as it was before that statute was passed in 1982. Three circuits have taken the position that the question is at least as much procedural as it is substantive, that use of the federal statute is not likely to encourage forum shopping since the rate varies unpredictably, and so that the federal statute should be used. Roy Stone Transfer Corp. v. Budd Co., 796 F.2d 720, 723 n. 6 (4th Cir.1986); G.M. Brod & Co. v. U.S. Home Corp., 759 F.2d 1526, 1542 (11th Cir.1985); Weitz Co. v. Mo-Kan Carpet, Inc., 723 F.2d 1382, 1386 (8th Cir.1983). One circuit may have taken the opposite stance, although from the opinion’s language it is just as likely that neither party raised the issue. Davis & Cox v. Summa Corp., 751 F.2d 1507, 1522 (9th Cir.1985); see also Lazzara v. Esser, 622 F.Supp. 48 (N.D.I11. 1985). Since the Seventh Circuit has held that federal common law applies to a somewhat analogous question, the standard which a district court sitting in diversity should apply in determining whether a jury award is excessive, In re Air Crash Disaster Near Chicago, 803 F.2d 304, 318 n. 12 (7th Cir.1986), we think that this circuit will side with the majority and apply the federal statute. Post-judgment interest here will be governed by 28 U.S.C. § 1961.
In summary, defendant-counterplaintiff is awarded the contract price, $5,497,291.81 plus interest at the prime rate plus 4% from July 1st, 1985 to the date of this judgment, pursuant to 113 of the Coal Lease Purchase Agreement. Post-judgment interest shall be at the rate set by 28 U.S.C. § 1961. Plaintiff-counterdefendant is entitled, upon satisfaction of the judgment, to an undivided fractional interest consisting of the right to mine 462,000 tons of 1990 reserve coal pursuant to 111 of the
