Good to know: selling products with a different condition is currently only possible at bol.com.
It is important that you give your products that have a condition other than 'new', a condition to bol.com. Besides this condition, you also need a separate description of these products.
You can place this data in your webshop with the products, or you can create it in EffectConnect using custom attributes.
Next, you can link these fields by choosing 'channel manager' in the left menu of EffectConnect, editing the desired bol.com channel, and then choosing 'delivery time settings'. On this page, you can select the desired attributes for the condition and the different descriptions.
Please keep in mind that the conditions of your products must be in line with the conditions supported by bol.com. To find out which conditions they support, click on the information bullet next to the field where you link the condition.
