How should I markup price columns and setup fee according to schema.org

Question

In the promotional products industry, an item will be offered at a certain price with a minimum quantity. Then, there will be another quantity level after which the price per piece goes down. There might be 5 or 6 of these levels.

In addition to the price per item, there is almost always a setup fee because they are being custom printed.

How do I mark this up using schema.org vocabulary?

Answer 1

Try using schema.org/Offer class and its property eligibleQuantity

Description of eligibleQuantity says

The interval and unit of measurement of ordering quantities for which the offer or price specification is valid. This allows e.g. specifying that a certain freight charge is valid only for a certain quantity.

Seems it's what you need. Markup may look like this

<div itemscope itemtype="http://schema.org/Offer">
    <span itemprop="price">$55.00</span>
    <div itemprop="eligibleQuantity" itemscope itemtype="http://schema.org/QuantitativeValue">
        <span itemprop="minValue">1</span>
        <span itemprop="maxValue">5</span>
    </div>
</div>
