Hello,
I bought a new one, sim free (actually it's dual sim which was a nice bonus !) on a couple of months ago.
It took about ten days for delivery, but otherwise no problem and was definitely the cheapest I could find, when I checked around for prices.
They operate a "refer a friend" programme, where they give you a discount code each time you refer a friend. I have received a couple of discount codes for referring friends and family (each for €5 off) and won't be using them before they expire. If anyone would like one, please send me a private message and I can pass them on. Absolutely no strings attached, just whatever website terms and conditions apply.
Other than being a satisfied customer, I have no other connection with the retailer.
