I've been shopping here regularly for some time and I've come to notice the positive things about the store. The produce is quite good given the fantastically low prices. Every so often they won't have what I need such as on a recent trip they did not have any shallots but when I asked someone to help me find them he was very accommodating and apologetic when he found they had none currently.
The people who work at the store are efficient but friendly and do what they can to help you.
At the end of the day, you can't beat the prices. And you make the trade off for what you get. I just go to the other grocery stores for what I cannot find at Aldi.
