This is the first time flubit haven't been able to get me a better price actually.... Their response was: We're really sorry but the offer on the link you provided us with is from a supplier who does not currently meet the standards Flubit requires in order to supply goods to our customers.
Unfortunately, we won't be able to create you a better price than the link you provided us with because we create our offers to be lower than the link you give us. If the link is too low due to the reasons stated above, our suppliers are unwilling to create better offers.
I've bought quite a few things via them. For example I saved £10 on a Transcend WiFi SD card once.
I'll work out how much I need to order and keep you guys posted
