Why would you not go to the grocery store?
Are you trying to run it so cheap that a few pennies for a bulk discount is the only way you can make it work? And Chinese, are you kidding me.... Not trying to be an A** but the quality should be more of a concern to you for your pax than a few pennies.
In the big scheme of things (total cost of operation), this is nothing. You should focus your efforts elsewhere.
just my opinion, do with it as you like.
