If you have the Airwick Electrical Diffusers, then you know the refills can be quite expensive. Tesco have them £3.85 for one. However, at the moment they have the whole unit, including the plug in at half price at £2.49. This is a good price itself, but what's more is that they are special edition packs with 100% free! Thats 2 plug ins, and 2 refills for just £2.49!
The Tesco site just mentions the half price offer, and doesnt say that you will get twice the amount, however my online shop did arrive with the 100% free packs. Might be worth picking them up in store as you cant guarantee the 100% free packs online.
