S 25 EXPENDITURES.
   Until otherwise provided by the City Commission, the City Manager shall act as the purchasing agent for the City, by whom all purchases shall be made, and who shall approve all vouchers for the payment of the same. Such purchasing agent shall also conduct all sales of personal property which the City Commission may authorize to be sold as having become unnecessary or unfit for the City's use.
   All purchases and sales shall conform to such regulations as the City may from time to time prescribe; but in either case, if an amount in excess of $1,000 is involved, competitive quotations shall be obtained. When it is anticipated an expenditure will exceed $10,000, formal competitive bidding shall be required; no such expenditure shall be split up for the sole purpose of evading this requirement.
   When purchases or sales are made on joint accounts of separate departments, the purchasing agent shall apportion the charge or credit to each department. He or she shall see to the delivery of supplies to each department, and take, and retain the receipt of each department therefor.
   Real property owned by the City may be sold or leased by the City without the need for competitive bids. Negotiations for the sale or lease of City property are permissible, where deemed appropriate by the City Manager, for the benefit of the City.
   Competitive bidding shall not be required where the purchase consists of supplies, a replacement part or supplemental parts, or services for products, equipment or property owned or leased by the City and the only source of supply for such supplies, parts or services is limited to a single provider.
   When an expenditure, other than the compensation of persons employed by the City, exceeds $10,000, such expenditure shall first be authorized and directed by ordinance or resolution of the City Commission, and no contract involving an expenditure in excess of such sum shall be made or awarded, except upon approval of the City Commission.
