Just a heads up to spend money but the May the 4th Lego promo is running again this year. Nothing amazing on offer (that I have heard), a nice Han Solo MiniFigs with £50 or more, free shipping and a poster. The new Red 5 X-Wing will go on sale (£170...) and apparently the B-Wing will be at half price due to what even Lego call poor sales. There will be some 10% off some other SW lego sets as well. There is always the hope of a better deals, who knows but on the surface it looks average at best, even so I think a Red 5 X-Wing is in order.
On the superhero front i think there will be an exclude Iron Man polybag at the end of the month with purchases, also see images of a Jor-El polybag but no idea what it will be promoted with.
