Is there a reason to peel onions for storage or sale? I typically try to buy organic onions.  Recently the only organic onions that are available are already peeled (i.e., have the outer papery skin removed).

Why is this being done? 

Presumably there is a cost to peeling the onions for the consumer so there must be a benefit either for the consumer (although none comes to mind) or during the processing of the onions.
Combination new technology and an excuse to charge more.  

It seems to be a 'value added' feature driven by new technology in processing harvested onions and the 'convenience' of not having to peel the Onion.

According to fruit today this is a growing market.  As others have noted sometimes Organic means an excuse to charge more.  Peeled onion aids that front.
