Argos are selling Toy Story Buzz Lightyear Pyjamas with glow-in-the-dark detailing for an amazingly low £2.99. I have seen these pyjamas come and go in the last year or so at Argos, but they are back in stock and are for sale at their lowest price ever!
Sizes go from 18 - 24 months all the way up to 4 - 5 years. The main link will take you to the smallest size and then you need to use the drop down size box to choose the size you need. Each size has it's own item number so I can't put them all on link I'm afraid.
Strangely for an Argos deal there appears to be stock in just about every store, and in all sizes in the areas I have checked as well. If each store only has limited stocks they might start to sell out quickly, but right now these Buzz Lightyear Pyjamas are widely available.
I have no idea what the glow-in-the-dark detailing involves but for £2.99 I'm not really bothered as that is such a good price for any type of pyjamas!
