Why do they have a senior support line, i..e., how is it different from their regular support line?

I noticed that I can add my Safeway membership number to the order to earn gas credits. But since they have their own pricing for Safeway products, presumably I won’t get any of their “deals” pricing that require clipping a digital coupon in the app? Or a moment ago I saw a $10 off a $50 purchase coupon in the Safeway app that I “clipped” (and now I need to remember to buy some staples tomorrow to get above $50).
