The merchandiser roles list 3 locations, is it the region around these areas or is it that specific?

For example the one listed Burys St. Edmunds, Thetford & Dereham, that I have applied for, would it be safe to assume this covers most of East Anglia?

Hi, that will refer to the areas you will cover in this particular role. We cover the whole of the UK but each rep will only be responsible for a particular geographical area like you have mentioned in your question.
