I have an account with UPS, with that I can order Security boxes (plain boxes opening on each end) Perfect for clothes and smaller items.7x9x3 12.5x10x3. I can also order label sheets which I use for all my packages...all postage is done online, print, stick on package and out the door it goes.You do need to ship a few things thru UPS to keep your account open, and I do this especially on some of my larger and heavier items. I can get better rates at times with UPS. I also use alot of Poly Mailers which I purchase for pennies on Ebay. Of course every trip to the grocery I have a load of boxes that I pick up as they are stocking groceries.
