Thursday just gone Lidl had car accessories on offer.
An intelligent battery charger for £13.99
A 1Kg Fire Extinguisher for £8.99
A cordless spotlight/torch for £16.99
Temperature and battery monitor for £2.99
Plus the usual 12v lighter plug extensions.
May be worth having a look before Monday's new offer if you're in the market for stuff for the boat. The 1Kg Fire Extinguisher is always handy.
