Its a bit early, but they tend to be about £1 a time at the end of the season But if you have a card already 8 for a tenner is pretty good this early. There will work in the Aldi stove currently available for a tenner too.
This deal with the stove for £20 isn't too bad... Heat (pun intended)..😁
8 cans of this stuff for a tenner is a bargain, if you already have a card and can get to a store to pick em up. Was gonna post it myself, but forgot. Heat added. (Four cans for £8 went hot last week.)
