Looks as though the glitch has stopped working now sadly...
I'm not going to waste too much time talking about this as stock is flying off the shelves! Basically the code LEGO5 is supposed to give you £5 off when you spend £30 on LEGO at Argos BUT if you select different items and use the Fastrack option, it's taking £5 off EACH item, even when your total is less than £30. And for items less than £5 (i.e. the small Lego packs at £3.99 like the Lego Friends Puppy Treats & Tricks*) you only get charged one shiny penny!
There's not really a lot more to say here, stocking fillers for Christmas, little extras to add to birthday gifts or just something to keep the kids amused over the holidays, for 1p you can't really go wrong!
What are you waiting for? Go, Go, Go!!!
