We are still battling the bugs with the new site. Currently, it's been discovered that when you search for an item, your cart will be cleared. We are trying to resolve this and a batch of other cart problems shortly.
The SFE site was down this morning for a few hours (sorry!). It seems that one of the global servers for currency exchange rates went down and took Spark Fun with it. Who would have thought? The currency conversion will be back in a few days.
Please do email us if you have any problems. We need to hear about them!
