Found a nice garden furniture set on the Homebase website and found the exact same product (with a different name) for £100 less in Argos with a 5 day delivery waiting time.
the Homebase set is £249 but with the Homebase price match guarentee they will match the price and give a 10% discount of the difference so £139 in total.
The Homebase link: http://www.homebase.co.uk/webapp/wcs/stores/servlet/ProductDisplay?langId=110&storeId=10151&partNumber=724817
The Argos link: http://www.argos.co.uk/static/Product/partNumber/6524793.htm
If they try the old trick of "It has a different name" then please quote there price check policy of... "•The product(s) must be comparable in style, quality and structure"
The items are exactually the same so they have to honour the price.
Now the free parasol base, on the homebase link click on "customer reviews" then a picture of a conrete parasol base will appear as a "we recomend" product.
Click on the picture and it will show you a price of £0.00 try and get them to match the price in store.
It didn't work for me, I think it was the managers time of the month. but with £110 off a garden furniture set, I couldn't complain! lol
