food for rescues

Our government has put a ban on import of petfood , this has made shops put the price of pet food up more than triple , they said it is classed as a luxury!! 

I need your help as I need to but pet food in bulk so we don't run out , I have over 100 cats, 10 kittens and 7 dogs ,I am looking for supplier that charges usual cost instead paying the stupid prices in the shops 

Please once again help me to help them . I need to buy few months food at once so I know all will be fed till hopefully something changes 

Thank you so much
