Very efficient. We have never had any problems with any oder from Overstock.

Service was 4 Star. Product was placed in a plastic ziplock type bag and as memeroy card users know these cards are sold in their own plastic case to protect them from static electricity and to keep them clean. This was not the case as mention above. The card did format in camera okay but I had to pay an additional $2.99 from a local merchant for a plastic card case.
