You're doing it wrong, then. Never ever use the mass entry/cart optimizer, it's fucking trash. First, search for one of the cards on your list, then click on one of the shops that offer free shipping to shop exclusively from them (pic rel). Then put in each of your cards one at a time and see if that shop has it, making sure to hit the $5 limit for free shipping. It's painful and tedious and takes forever but hey that's how you get free shipping. Several years and dozens upon dozens of packages and not once have I paid for shipping from TCGplayer
