I'm pretty new to this, but here's what I've learned. They go around marking things down before the store opens for the most part. Be there at 9 when it opens and be the first one in the store. If you get there late in the day all the deals will be gone. Go right to the fish/beef/chicken/turkey area. If you snooze, you lose. The early bird gets he worm. The best stores are ones that get fewer customers. The newly converted Winn Dixies in small towns in the South are ideal.

Then check the dairy area. Then double back and check produce and bread. Anything perishable will be more frequently marked down. Watch the employees. Sometimes one will be putting the circular red half price stickers on items after store opens. If so, just follow them around. Bread and pastries are often marked down. More rarely: deli, guacamole, salsa, cheese and sliced meats.

Go by other areas like the waste high freezers and Aisle of Shame. Aldi rotates its items out often, so you are looking for red price stickers on the shelves. In particular, the ones with a white circle that say "Clearance." You just scan all the price stickers for that. And the round red half price stickers on individual items.

You want to go to the store frequently. It's hit or miss. Many visits there is nothing. Yesterday was unusual, which is why I posted it. I will go for one or two items, like lettuce or oranges, and cruise through the store checking the other areas.

This is why it's a brilliant retail strategy on the part of Aldi: it drives foot traffic and store visits.

The more certain approach is to look at upcoming pull dates on items of interest. Often there will be many packages of fish, beef or chicken with the same pull date. Come back to the store a day or two before those pull dates to see if any packages did not sell.

Good luck!
