Always avoid cheap meats as they are the product of cruelty. It can be hard for some to accept at first but the ideal diet is vegetarian or even vegan.
If you are one of those who cannot accept this yet then at least avoid the cheap meats. It is morally wrong to keep animals in appalling conditions just to lower the price of their dead bodies. Vote with your wallet/purse and do not pay those who want to maximise their profits at the expense of weaker creatures.
Cheap meats are bad for your health and psycholgical wellbeing both of which effects will cost you in the long run.
Eat wisely, eat vegetarian/vegan foods.
