Tesco Clubcard and Boots Advantage both seem pretty generous if you play the system (for example, swapping £10 of Tesco points for £30 or £40 of Wightlink travel), whereas Nectar seems to get less and less generous every year.
After a decade of shopping at Sainsbury's we had nearly enough Nectar Points to buy a 400g punnet of strawberries. I exaggerate only slightly.
This week Red Funnel launched its own loyalty card - My Red Funnel Rewards - which is free to anyone who fancies it. But is it any good, or another card in your wallet that you carry around everywhere and never actually use? (I tried to use my Morrisons Miles card recently, only to be told it had been discontinued many months ago).
Isle of Wight Guru's elite team of hotshot lawyers (the wife and I) have spent the last day poring over the terms and conditions and have concluded it is one of the more generous loyalty schemes around.
Pretty much every £1 you spend with Red Funnel will earn you 4 points (worth 4p) if you are a mainlander or 5 points (worth 5p) if you are a 'permanent' Isle of Wight resident (it is called My Red Funnel Rewards Plus for Islanders). Second home owners are stuck with 4p per £1 I'm afraid.
Once you've accumulated 300 points you can start spending. That means you need to spend £60 as an Islander or £75 as a mainlander, which you will probably do in one car return journey during the summer months.
You can then use your points on future Red Funnel travel or just splash out on a couple of onboard sausage rolls. So, if you spent £100 on a Red Funnel car journey you would get £4 or £5 on your card.
The points expire five years after they were added on so it wouldn't matter if you only visited the Isle of Wight every couple of years.
Red Funnel Season ticket holders and Red Funnel Travel Card users seem to get points, although they can't be spent on future season tickets and travel cards. By my calculations, an Isle of Wight season ticket holder would accumulate £124.15 worth of points from a 12 month Red Jet pass. They could spend that on a car journey or two. Leave a comment below if you think I've got that wrong, but that's how I understand it.
The loyalty card is only for bog standard travellers. It's not for freight, company accounts or for vans over 5.5m long or 2m tall.
As part of the launch, they are also doing a promotion with some extra points on offer (£20,000 worth of points are being split between everyone who signs up in August).
Based on how other loyalty card schemes I would expect them to do some other promotions along the lines of double points for travelling at 3am on a Thursday in March and so on.
The only thing that might put people off joining is that you are obliged to receive emails about the scheme (you can't opt out) but it does say they won't flog your details to third parties without permission, so it is pretty standard stuff.
So would it persuade me to choose Red Funnel over Wightlink? Personally, I would see it as a 4% or 5% discount and work out which is cheaper with that in mind.
