I got behind a chick at Sam's (when I was in a wicked hurry, of course), who proceeded to pay in small increments over several debit or gift cards. $5 here, $12 on another, $7 on another, etc.
The annoying thing about Aldi's is the no bags. If you don't remember to bring your own, you'll have all these various items rolling around your car floor. I was quite happy with their produce quality and prices, and the meats (like a pork roast) were just fine.
