I like this place, it's convenient, and there's a large parking lot behind the building (the front of the store is actually not on Springfield but around the corner on Stoughton). They have the short 2-layer shopping carts that I like.
You have to be careful when checking out because there will be signs up for things on sale, but they won't ring up on sale. Watch your receipts because I don't always catch it until I get home. But they are very friendly and will fix it (if you catch it). Sometimes the self-checkouts are more hassle, but if you don't have any produce it's not too bad.
The store is open 24 hours (fabulous) and I love Caribou Coffee (not sure how late they serve coffee, but you can stay there all night). Free Wi-Fi. And *free refills* on coffee while you are there studying. :)
