PayPal unveiled deals with 15 retailers including Toys R Us, JCPenney and Barnes & Noble, helping the online payment giant expand into more physical stores.

The deals add to a pact with Home Depot, which began accepting PayPal in about 2000 stores earlier this year.

One of the most important sources of future growth for eBay-owned PayPal may come from its expansion into physical stores — a much bigger market than its online roots. Other retailers included Office Depot and Footlocker.
