Sorry if this topic has been discussed before, but I did a search and found nothing about it. So for all ebayers, where do you guys usually buy the shipping boxes to pack the Lego box? I am looking for shipping boxes where the dimension looks something like the ones shipped by Amazon, about 24"L x 17"W x 6"****. I checked Walmart and Target, they only have the cube-shape boxes, they are too tall for just one Lego set. I also checked FedEx office but they are way too expensive. Any suggestions?
