Three quotes or bids are required for any single item that is more than $1,000 in your budget. For example, if you need to purchase 200 books at the cost of $1,200, you would NOT need a bid because each book costs less than $1,000. If you need to purchase one piece of equipment that costs $1,200, you would need to submit at least three bids or quotes that demonstrate you’ve researched the vendor you’ve selected. Typically, any kind of construction cost (e.g. you are building a greenhouse) will require bids.
