There are always lots of brilliant offers for me, it's really got as good as Tesco Clubcard now and in many ways better. For instance, I have just had another 350 bonus points for booking any Virgin Train train. I get one of these seemingly every month. Also get Virgin East Coast ones just as much.
Also I had loads of free points just for using Virgin trains with them for a year - just had to click add to card.
It's worth scrolling right down and checking carefully. Always note down the date you did an offer and how many points are due. Then, if after 28 days the points are not on your account, go on Nectar Live Chat to get them. I also ask for compensatory points for inconvenience suffered.
I have activated one for an ebay offer. You must activate by today (31st) and on 2 September you must log into account again to find out what the offer is.
