Cancelling Shipping Accessories?
Recently, I purchased a Nikon D7000 with a Nikkor 50mm f/1.4D lens (as an accessory) from Dell. There was a notice on the lens that it may be delayed by 9 days before shipping. Two days ago, I received my Nikon D7000 from the delivery truck, but I didn't received the lens, yet. However, I'm considering of cancelling the lens and just buying it straight from Best Buy (since I found out that they have it in stock).
