I like this stuff, it smells good for apparently for 48 hours, not that i've gone to that extreme :)
This is for the larger 250ml can. I spotted it in one of the Cardiff stores and it's also available for delivery so is nationwide.
There are a few 'Aromas' available
The smaller can is still £2.44 and this can retails normally for about £3 and still is on the Tesco site, so for this price, it is definitely *ahem* "worth it" :)
