This roboreptile was £89.99 and has been reduced gradually down to £49.99. Use code PRICE10 to bring it down another 10%! It is only available on the internet as far as I can tell.
I missed out on these when they were around the £50 mark from Marks and Spencer and then the deal ended so thought I was going to have to pay a higher price.
This seems a good price to me though!!
Hope it helps some others too.
