Yes. Regular buyers get account pricing and a named contact rather than a general inbox. It is worth setting up if you expect to reorder more than a couple of times a year.
Trade accounts aren't just about price — the real value is a named contact who already knows your spec, so a reorder email is three lines instead of a full re-brief. For businesses reordering quarterly or more, that saved admin time is usually worth more than the discount itself.
The questions are free. So is the quote.
