[pickup_method] is optional to enable click and collect for your offers.You must supply values for the collection SLA [pickup_sla] attribute, and add values for the collection method [pickup_method] attribute as needed. If you do not add the collection SLA [pickup_sla] attribute to your local products feed, you may receive the error messages below.
Note: If an offer doesn't have both the collection method [pickup_method] and the collection SLA [pickup_sla] attribute, you won't receive any error messages because Google regards the offer as not eligible for click and collect.
