This is the link to sign up for My Bi-Lo, which is a portal to your own personal Bi-Lo site: Sign up for My BI-LO

By signing up and logging in, you have access to your store's weekly ad, promotions, your prescription refills, year-to-date savings and printable coupons plus other info.

In my experience, once you sign up for the my Bi-Lo, you cannot return to the regular BiLo website. From then on, the home page will always take you to your log-in screen by default.
