Take note some gazebos are advertised as pop-up which doesn't actually mean that at all, for example Woolworths have been selling one for 29.99 which you have to assemble yourself and doesn't come with side panels. This one that I have bought today does pop-up via a concertina system, no pole putting together business here but they are better known as EAZI-UP. See how much they go for on Ebay and compare.... don't forget this has side panels which are usually extra to buy also.
It says the offer is Thursday 29th May Special Buys, but doesn't actually say when it expires or if it is literally for today only.. So as usual I have guessed the expiry date, methinks probably when stocks run out. Got mine from Luton and they had plenty left.
