How to ship 0.50 cents or less MTG singles?

Started selling on Manapool recently and I've been mulling over how I should ship cheaper cards. For every single I've been shipping I've done, perfect fit, penny sleeve, toploader, team bag. Non machinable postage every time. Granted all my sales are $2.00 or more. If I was to get an order for a .50 cent card, should I skip the perfect fits and team bags?

As far as non machinable goes, I'm wondering if it would be okay to ship 1 or 2 cards without non machinable postage, but everywhere I've looked online makes it seem like anything with a toploader should get non machinable treatment. Of course I don't mind doing it for a single 30 dollar card, but if I begin listing my bulk and getting orders for .15 - .30 cent singles, do I really need the extra postage? Or will the cards be okay? The extra postage basically forces me to sell at a loss or increase the price floor on cheap bulk singles to roughly .50 cents.
