Need Help-Electrical Converter for Europe

[Stavs]

Wife is going to England on Saturday and I need to get her something so she can use her hair dryer and laptop. Here's the kicker...it has to be from Amazon.com so we can get it guaranteed by friday (for free since we have prime). Radio Shack would also be good, if I could pick up in store. I do not want to go to BB or CC due to crowds.

I looked and I dont really know what I am looking for.

TIA
