The question is about the first comma use in the sentences below. I have not seen such comma-punctuation in a sentence that continues with naming several listed items. Is the first comma in these sentences grammatically correct? Or should we replace this with a colon?
I bought several items from the shop including, tomatoes, bananas, ketchup, chocolate, cucumber, bread, butter, green tea and milk.
