Not a problem....just call Staples on the phone, and ask them to price match the Radio Shack offer (which they will). They will verify the online sale themselves, and promptly take your order and deliver it for free in 3 days or less via UPS.
One hour ago, 19.95 online offer at radio shack said out of stock online but in stock at stores. The first store said they didn't have it but to call other stores in area. Second store was more helpful and checked the area warehouse, which had the rapid charger in stock. I then went to my nearest Radio Shack, pre-paid 19.95 and it will be delivered direct to my address with no delivery charge. Thanks for the sale notification.
