Cheapest thing on amazon?

[jaffa]

Apparantly if i add 31p (56c) to my amazon order i get to take advantage of their free delivery.

not taking advantage of this will cost me an extra £2.70 ($4.90) in postage.

So OOT. What's the best thing on amazon that i could add to my order that's under £2.70?

Bonus points for the cheapest items.

Extra bonus points if i can combine 2 whole extra items for under £2.70!

Edit: The items should generally be in stock.
