Get your taxes done using TurboTax

Thank you. I’m struggling because I don’t buy the card itself, I buy many packs of cards in hopes of obtaining cards worth selling. So I might buy a lot of 10 packs at $5 per pack for $50, and only one pack has a card worth selling in it and the rest I throw in the trash. Can I deduct the full $50 for that one card sale in this example? Or do I need to account for the cards I disposed of in some way?
