Okla. Stat. tit. 23, § 23-92: Value to buyer or owner

In estimating damages, except as provided by the two following

sections, the value of property to a buyer or owner thereof,

deprived of its possession, is deemed to be the price at which he

might have bought an equivalent thing, in the market nearest to the

place where the property ought to have been put into his possession,

and at such time after the breach of duty upon which his right to

damages is founded as would suffice, with reasonable diligence, for

him to make such a purchase.
