OK first time at this after months of viewing so I hope this works.
B&Q will price match. So, I went to woolworth website, searched for trampoline then added the 12foot enclosure at £119.99 then the 12 foot trampoline at £119.99 to the shopping cart. view the total and it discounts to £149.98. But then it adds £24.95 for delivery getting you a 12 foot trampoline and enclosure including delivery for £174.93.
Thats not bad - but it gets better.
Print out the quote and take it to B&Q. They will price match the product price ( £149.98 ) then take an additional 10% off ( wow ! ) to get the price down to £134.96 -but say that they will not match the delivery - now that's fine by me ! So the catch is that you need to uplift & you'll need an estate car for that as it comes in 3 big boxes.
Now, even if the store gets wise and only discounts against the 'delivered price' it still brings the product down to £157.44 which is still great value.
In my opinion, B&Q's product is better than the woolworths & Toys'r'us ones.
Good luck with that, copy of my receipt on the image link, for reference.
Now - anyone in West Lothian know how to build a trampoline?
