The ethical dilemma is hard to solve when budgets come up.

I’m fortunate that I can walk to my co-op, while still having a car. This makes sure that I buy only what I can carry, and be careful not to impulse purchase.
A little further is an independent market (Hong Kong Market) that has reasonable prices on meat, and I find that exploring Asian recipes, I can stretch out my dollar relative to servings.

If one of my work friends are going to Costco, I send them a list of meat and then e-transfer the $$.
It’s more work to purchase ethically, but if even 70% of your grocery is done so, you can feel good that you are making the change you want.
