I have been purchasing from Nuts.com for about 10 years, primarily for ground sumac. Their quality seemed good and their prices were initially good. They recently virtually doubled the price for sumac and reduced their inventory to mostly snack foods. My latest shipment of sumac was not sumac! It was in a different colored package and had chunks of material with some light coloring. It didn't smell like sumac and it's taste was different. I complained to nuts.com. Their response was to simply give me a credit and not take the problem seriously. They didn't ask for a sample to analyze. So their quality control is zero. I will never trust this company again, and I think that you should stay away from making any purchases from them.
