Zaavi (at least in my local branch, Sutton) are selling the Samsung J600 for £39.99 instore, and this includes £10 airtime. It is generally priced at £40+ on the internet and £49.99 on Virgin Mobile's own site.
You can get this phone for even cheaper than that if you are a Virgin Mobile customer. With Virgin, for every £100 you spend you recieve £10 off a new phone (capping at £200 in bonuses). You can use this online, at http://www.virginmobile.com/vm/home.do
or you can use it instore; at Zaavi. If you go to Zaavi and give them your mobile number they can also tell you and this is how they can take off any rewards you have earnt. In this way you can use your bonuses on the £39.99 phone (£39.99 including £10 airtime) and then potentially reduce the phone cost to £10 airtime only. This phone for £10 is an amazing deal.
You can also check how much you can get off your Virgin Mobile phone by going to http://www.virginmobile.com/vm/home.do
and signing up or logging in (it's free) and click on "Your rewards". It will tell you if you are entitled to any money off. Alternatively, ring 789 then press 0 (calls at a flat rate of 10p) and you can ask an operator how much you have spent in the last 24 months (they only count the last 24 months in the £10 off bonuses) and see how far you are from an £100 mark.
This is my first post so I hope it helps!
The basic point is to use your rewards instore as the website is more expensive by £10 / £20 if you are considering the airtime and the rewards will benefit you more there.
Also, I got the phone for £19.99 (with a £10 topup) but I also topped up by another £10, so that I paid £29.99 to reachtheir current offer of topping up by £20 in July and recieving 300 free texts in August (although you may have to recieve an email or text directly from Virgin to be valid for this). The free texts made the deal extra sweet as I recieved free texts, a cheaper phone, phone credit and some chocolate from the store!!!!
