Ive just phoned B&Q and they have said that stock is being replenished over the weekend of all items that are out of stock.
Delivery is within 14 days and there have ben no reported delays of delivery of items that have been ordered and paid for.
They would not let me pay for the Mckinley as it is out of stock....so I couldnt gaurentee getting one
The items should be concreted in to place to prevent the items from falling over....DH has looked at the site and he reckons some large stakes would be fine to hold down the smaller frames.(The stakes are available from most DIY stores and are similar to camping pegs but larger and more robust).
So if you are desperatley trying to secure one of the items, its a case of logging in early every morning and being patient until stock is again available.
If/when the items are back in I will start a new thread to let you know.
