I had the same problem. The option for standard envelope wasn't showing up when I went to print the label. I've used it before in the past about a dozen times no problem. I ended up sending it with 2 regular postage stamps because I'm no going to pay $3.00 to ship an item that cost $2.00. Some sort of technical issue and nobody's fixed it, so I cancelled all my trading card listings until they fix it.
