So the xa2 is £149 which is a great price, couple it with the possible cashback of £50 being offered from topcashback, makes it even sweeter, now in my experience, the cashback tracks at £5, 30 days later I claimed, and it has always been uplifted.
I think some people have had different experiences than me, so never take the cashback as a given.
In the case of the 6t, the cashback (annoyingly) for new handset purchases, is £30, don't forget you will have to pay an extra £10, to activate your sim card, and therefore be eligible for the cashback. giffgaff.com/mob…ils
