This is cheaper than the one I listed for Aldi's except it doesn't come with side panels.
This is a very good deal seeing as some of the ones you have to assemble yourself with poles can be found for the same price as this, and IMHO are generally crap. I saw this deal in the Hemel Hempstead store today and it looks great.
I bought an almost identical one from Aldis at 49.99, and they are very easy to pop-up, as they work on a concertina style system and easy to put away also.
