I have a Sainsburys Credid Card and today I lost my slot to buy festival tickets because they chose to run a security check on the transaction (it was only for £411). This happens all the time and only several months ago they cancelled payment for a on line Asda food shop and once again I lost the delivery slot and have to venture out the next day to the Sainsburys supermarket! Frustrated I called to enquire and and was told that their system picks out any unusual transactions and puts a stop to them until you give confirmation that it is you making the purchase - all well and good it you not in bed when the payment is climes (the case with Asda, who I don’t USUALLY shop with, who don’t claim payment until midnight as you can still ament your order until 23:59) or where you have been fortunate enough to get on to a festival website and only get 6 minutes to complete your transaction). On the first occasion I made a complaint but more so because of the way and tone of the customer service person. It took them 3 month to respond and they completely missed the point and did little more than to justify their set up. To make matters more difficult there is no way to let Sainsburys bank know that you want to do something out of the norm. So in basic terms, if you want to be spontaneous and need a credit card to do it then Sainsburys is not for you as there is no way to be certain that the card will work for you. I have a NatWest card too and have had for many years and they have never left me hanging in the same way. The benefit if Nectar points just isn’t worth the hasstle so I’m checking out
