I always collect loyalty cards but have never bothered with the Sparks until recently as it only seemed to be about invite to view sales first etc. However, they seem to keep one major advantage hidden. Every so often they have a 20% off everything weekend. The next one is this weekend coming. You will never see it advertised in the store. I have had the card since about November and this is the third 20% off weekend. Well worth getting- but please note that you do need to go online to register your card for that promotion. They do send emails reminding you to do this. Its for clothes, beauty, furniture and home. Read the exclusions as some brands are not included
