Depending on what you are shipping, you may want to look at boxes directly from the USPS. When I was doing eBay I would ship all my items priority mail. I did this for a couple of reasons. First, the Post Office provides Priority mail boxes in a variety of sizes for free. Second, I could track the items and didn't have to deal with "I haven't received it yet".
As far as packing materials around the items I used old newspapers and also shreaded paper (I had a shredder that shredded in strips, so I made my own.) I also used bubble wrap and peanuts where needed. I bought from various locations, just wherever I could find a good deal.
Hi I am run an online store on ebay. There are a few orders everyday to ship out. What shipping supplies you will choose to wrap? What shipping supplies are the best cost-effective? Where can I get good quality shipping supplies at reasonable price? Are there anyone has experience with this? Thank you for your share.
