Normal price appears to be around £90, which is doubtless a bit inflated because they look pretty. But this does seem like a decent deal for a portable USB/mini USB device charger.

This price only applies to the turquoise one. It doesn't show up on the page, but it will when you put it in your basket.
There are UO discount codes available if you poke around, nothing spectacular but you can probably knock the price down a little. Enjoy:)
