I just went into my local Tesco in Carmarthen to try to buy an Apple lightning to 30-pin adapter for my dock. They are £22 online in Tesco but they didn't have them in store. But the sales staff on electrical said they had the cable ones in stock.. I thought that would do the job and when he said they are £7.50 I snatched his hand off, they are £35 at the Apple Store.
They are the official Apple product.
Before the Apple haters start, I am just trying to help someone who needs one of these adapters.
He said that they had plenty in stock and thought it was a nationwide price. Hope it's not a Wild goose chase for anyone..
