I used this site to buy a paddock stand recently. They delivered quickly and were the cheapest for what I wanted. I keep getting discount code e-mail and this may come in handy for some of you. *After logging onto the site, the code is on their homepage, available to all. I'm not as special as I thought. https://www.motea.com/en/
As Jack as it sounds, pretty much any retailer will have to give you discount if you put it on them at the moment.
