I purchased some products of Astrum Computer Group - Online Computer & Mobile Shop
and was absolutely amazed on the service and also quality in the products that they offered. They are based in Lee On Solent, Gosport.
I purchased a Vexillum PC, Nintendo Wii, and a Nintendo Wii Fit and received them the next day.....excellent service.
I did notice that they sell contract mobile phones and also pay as you go phones and will definitely be using them for this as well. They also do weird and wonderful things as well, would recommmend any one to have a look.
