history: I saved up so much shopping at Aldi's ! So i used to shop in walmart and i thought it was the cheapest place to shop at but yesterday i went grocery shopping at aldi's and i was so surprised to see how much cheaper it is to shop there
current: I thought walmart was pretty cheap.  I've never been to aldi's
next: you should give it a try! They have their own brands which are super cheap and the quality is great
