Here is what is going on with Games Workshop, as far as we can tell. Early during the pandemic, the entire company shut down and restocks were unavailable. Around early May, they started again and shipments were pretty timely. Now for the last two months, restocks of regular products have taking 2-3 weeks to arrive. New releases arrive on time but we, for the past month or so, have had to start putting new release orders in the Thursday or Friday before the release date to make sure they arrive by Saturday.
Part of the problem is the supply chain. GW prints all of their books in China so restocks of books, once they sell out, are taking 4 to 6 months to arrive. Restocks of miniatures take about 1-2 months to come back into stock.
GW also says that, due to COVID social distancing, they are short staffed at their Memphis warehouse so shipments take longer and require more lead time to get packed. However, we have not seen similar problems with our other suppliers who still manage to get our ordered out on a timely basis so not sure how much credence to give this.
