Where is the most cost effective place to purchase shipping boxes and mailers for MF orders? We tried using value mailers but weren’t impressed with the quality.
You can get some free mailers and boxes from USPS I believe. We use a mix of U-Line shipping supplies and USPS mailers/boxes.
You may also want to search your area. I found a box manufacturer close to me, and I’m nowhere near “paper mill” country. Their prices are similar to online prices BUT I can get free delivery the next day or pick up myself, and they offer misprints and overruns of custom boxes stupid cheap (so they might have a random company name on them but still a new box) or just get cheap shipping labels via labels.vs which can help you to save your money.
