I repeatedly purchase from them and I am repeatedly happy

As always, the products i receive from Battery Space are top-notch. I repeatedly purchase from them and I am repeatedly happy. The only downside is that shipping is expensive and slow. With that in mind I try to order early and get more stuff in each order.
