If you don’t want to display the offers which don’t match your price policy, you can use price filtering in your plugin. To do it, you need to add specific tags, which you can find below. You can use one or both tags.
Bottom price limit
data-bb-price-bottom-limit="{bottom-price}"
Top price limit
data-bb-price-top-limit="{top-price}"
Example
This widget (plugin) will show only the offers priced between 640,00 and 665,00.
<div
class="bb-widget"
id="buybox-7djt"
data-bb-id="1123"
data-bb-number="5906006234744"
data-bb-price-top-limit="665.00"
data-bb-price-bottom-limit="640.00">
</div>
