Spotted these today which I'm well addicted to: 15ml Sudafed decongestant nasal spray (xylometazoline) (This is the metered dose glass bottle type)
Looks like its only in-store at Wilko's for £1.57 which is a VERY good price I reckon... I normally pay £2.78 at Morries and the other bigger chains. Normally this is more than £3 at Boots.
Bought myself 4 bottles to stock up for a while as I'm not sure when this deal will end. :-)
