Re: Cheap shipping???????
BTW - the configuration I use lets me ship up to 24 cards and still be under 3 oz.:
4x7" bubble mailer
Thin piece of cardboard (e.g., back of a blister pack for headphones) to keep the flat stiff (for those sticklers at the post office)
Two top loaders (not the uber-flat ones, but not the super thick ones, either)
One sheet of notebook paper (wraps the top loaders/card "sandwich" so they don't get gummy with tape, or get loose)
One small piece of tape (keeps the paper wrap shut/tight)
24 MTG cards (sleeved, mostly in penny sleeves)
PayPal printed shipping label
Packing tape on all four sides of the shipping label
