I buy there because i work there, discount!
But others will as some just prefer it, and if its close by, then people will obv just go there instead of travelling
as for me-
1) wide aisle-comfort
2) more open cash reg.
3) groceries quite cheap
4) good maintained trolleys
some others dont provide those things...
Because it is the only shop within walking distance of my home that is open when I get home from work.
Because it's the most successful supermarket for a reason! :D
Say NEIGH to Sainsburys! ;)
Because they have the items I want, is near my home and has parking.
A lot better than ASDA.
