Erm, not sure how to describe it more than the title really... Pack of 15 Pasante Dotted Condoms (the texture, not a polka pattern) instore at Tesco for 87p. They expire in 2013, allowing you approximately 5 good times a year. In fact, better than good as these are "dotted for extra stimulation", so yay I guess.
All other Pasante brands were more expensive, it's only this type that were so cheap. I'm well aware that they are available for free from Family Planning clinics, but they do not tend to be open at night, and Tesco don't ask me awkward questions.
Found in Trent Vale Tesco, but not on the shelves in Longton Tesco so I'm not sure about nationwide availability.
