I think it interesting that the person who has the highest feedback rating on eBay sells packing materials. His seller name is parrothead88 and his current feedback rating is 27,412. He sells new bubble wrap along with boxes and mailers. His prices on eBay are more reasonable than his online store. I use recycled materials for shipping. I can buy used large and small bubble wrap and quality recycled boxes from a company in Portland, OR called Carton Services. They specialize in new and used packing materials. I am certain that any large city has a packaging materials dealer where you can get quality used packing materials. The used bubble wrap I buy come in a bag about 2+ feet by 6 feet and cost $15. The last bag I got was half pink. Yesterday I went by to get more and they were out with no idea when they will get more. I had to buy a roll of new. At Carton Services they also buy and sell cardboard cartons. Yesterday I bought two boxes the exact size I needed for $2 each. They had been part of an odd lot that they had bought, second hand but never used. I have sold them boxes also. Once I bought the contents of a shipping room at an auction. I got two pickup loads of new boxes that I sold Carton Services. I kept enough for me, sold the rest. there are quality recycled packing materials out there if you can look for them. I should also mention The US Postal Service. If you ship Priority or Express Mail they will give you boxes, tape and labels. I use this almost always for shipping circuit cards. The large flat priority mail boxes will hold up to 4 S100 cards or 2 quad Qbus cards. (to keep this on topic). I wrap or bag each card in anti-stat then wrap with large bubble. I have had no problems so far. Paxton Astoria, OR
