No, I can't say that I source all my food from the same company. In most cases some companies do offers on food which can really be a help at times and some of the deals they do are always great, so I never really want to miss out on that. I have found that there are around 3 different companies that I use myself that I have no issue with and that I have used quite regularly. I feel that if you can find at least a few companies that are good with their products and also do good service and good deals it's wise to have that.
