Morrisons is close by, you'll probably see it when you arrive. It's on Tritton Road, come out of the uni and there is one main road, follow that and your there. Can't really miss it. There's Tesco's a bit further , Lildls is closer than Morrisons but I don't think it's any good. Sainsburys, Asda's and a larger Tesco's are quite far from the uni though and you'd need a car/bus so not worth it. Most students seem to stick to Morrisons/Lidls and sometimes Tesco I think. Used to work in Morrisons and last years freshers weekend was absolutely heaving on the Sat/Sun so it's probably going to be a bit hectic today and tomorrow.
