not sure why you deleted post
but if you put down what you usually feed and use for beddign and cleaning we may be able to help
General..ask friends family for old newspapers for hutch.
Buy a supermarkets cheap vinegar..in Asda about 13 p a bottle..and use that for disinfecting litter trays etc..rinse well
Which pellets/mix do you use? Wagg Optimum are ususally cheaper than most other ones and are good quality..buying a larger bag and storing in a sealed container can save quite a bit.
Ask neighbours if they can give you any veg cuttings/outer leaves of veg that they may throw away..aslong as they are not mouldy and you rinse them they will be fine
If you have friends who visit and like to see the bunnies ask them to bring a carrot with them if they want a cuddle!!
Going to find your own free greens is a good idea but do not pick weeds from along roadsides where councils will have sprayed..be careful about where dogs could have pee'd ..and check you know what you are picking
