Where to find zeigler rat in 50s

I've checked zeigler's site, their where to buy link and many places on the net but cant seem to find the large 50lb. bags of their rat food. just their cans and 4lb bags. Anyone know where to get/order it from. I know they make em. especially for those going through large quantities of it.... Ralph to name one.

Bump
zeigler or mazuri big bags? Anyone.

I found some but would like a referral to a reliable place to buy from as well as good pricing.

Where are You located?

For Mazuri, try their store locator. It might take you a few phone calls to get someone who knows what you're asking for, but chances are good that there's something nearby that can order in those 50 pound sacks for you. I drive 20 miles to get mine, but I buy a few at a time to offset the trip.
