I have 4 reciepes from T & T, there were 2 having pricing problem, I beleive it caused by cashers.
One leg duck theory:
chicken/duck leg doesn't taste good. We can see the price for this part is quite low. They suppose to take away both legs,
Reason to keep one, my discovery:
1. it is easy to cut, you can hold the leg.
2. it is easy to eat as whole, you can hold the leg.
I'll check it out the duck in my fridge. If there is one leg, I think it is a bonus for me, if there are two, I would consider there are two bonuses for me.
Don't think about "Feng shui". Any food is a pleasure to us.
