I suspect it's probably shelf life more than anything else--if they keep just enough stock of them that they're constantly being bought and restocked, they don't have time to sit on the shelf and wilt.

very thin profit margin, tough quality checks (when delivering the items to the warehouses the checks were done on many more samples and in a much more detailed way than what other supermarket chains did) and if the truck arrived at the warehouse anytime after the agreed delivery time you were basically screwed (ranging from at least having to provide a discount to the whole delivery being rejected therefore having to find another chain willing to buy it or just throw it away).
All this might as well explain (additionally to your "shelf life") the good & cheap onions.
I'm an onion lover - Go onions! :)
(ps: this is just a neutral comment - so far I mostly ignored Aldi, excluding the exercise bike I bought from them which is still working perfectly ~3 years later)
I mean, compared to $400 HPs or $200 Samsungs, there's definitely more attention to detail, but that isn't exactly a very fair comparison.
I'd argue that the whole consumer electronics industry is negligent, including Apple.
