Aldi is a German-based retailer. The vast majority of its products its own store's brand, which in addition to other aspects of the shopping experience, helps keep prices low. I go to Aldi about once a month. It's usually when the big stores' ads are lacking. I thought I'd compare the prices I paid for these items to what I would have to pay at Publix or Winn-Dixie.
($3.50-$4.50 for regular store brand, $6.99 for Oscar Mayer or Hormel)
Chunk Tuna in Water, $0.52
Green Peppers, $0.79/ pack (Sale)
This was a little over one pound. So, you're talking $0.85 or so a pound. Regular price is $2.49/lb at the other stores.
($1.90 to $2.49 elsewhere)
2lb Yellow Onions, $0.79/bag (Sale)
($0.99/lb sale price at Publix this week; would have been $2.00)
Tomatoes, $1.29/pack (Sale)
($2.99/lb elsewhere. This is 1.25lbs, so it would have been up to $3.74 elsewhere)
($1.99/lb elsewhere; at 1.5 lbs, this would have been $3.16 elsewhere)
Dozen Large Eggs, $1.29
So, I saved between $8 - $10 over what I would normally pay at Publix or Winn-Dixie for these items.
