Be sure to list all of your Trading Cards for eBay Standard Envelope shipment as Trading Cards. I chose MLB Sports Cards and Memorabilia as the category for one of my card listings. eBay wouldn't allow me to choose eBay Standard Shipping for it. Kind of crazy since Sports Cards and Trading Cards (I fail to see the difference) can have memorabilia in them, weigh less than one ounce, and sent in a Standard Envelope. So I plopped a 52 cent stamp on it. Just a word of advice.
