I’ve been a customer with M&M for a few years now and find them excellent. I only get milk (cow and oat) so can’t comment on other products.
The milk deliveries are great, on time and the amendments (holidays, quantities, etc) are easy to do online. When I had an issue, they responded quickly and were very helpful.
I really like that the bottles are re-used so no more plastic cluttering my recycling bin.
I highly recommend the company.
