Tap it with a hammer, listen for a dull ring.

Just realized I've been paying the chicken breast tax for years like a total sucker. That whole bird move is genius, especially when you get a week's worth of meals and free soup out of the deal. My best switch was buying a big cheap pork shoulder and learning how to braise it, which feels like a magic trick for how much food it makes.

My last trip I rolled everything and still saved fifty bucks on baggage fees.
