If proposals are so invited, the bonds should be awarded to the bidder offering to purchase the bonds at the lowest net interest cost to the County, the net interest cost to be determined by computing the aggregate amount of interest payable on the bonds from their date to their respective maturities and by deducting from such aggregate amount the premium offered, if any.(h) Pending the preparation of the definitive bonds, interim receipts or certificates in such form and with such provisions as the county government determines may be issued to the purchasers of bonds sold pursuant to this chapter.(i) The rate of interest may be determined in advance of sale, or the bonds may be offered for sale at a rate of interest to be fixed by the purchaser of such bonds.9 Del.
