Stuff we use -

ACSI - Out of season discount card for campsites across Europe.

Kyham - They sold us our house.  Great tents and for reasonable prices.

Alpkit - Camping and mountain equipment.  Most of our gear is Alpkit. 

MSR - Would really like a tent from these guys.  We could only afford pans.  But they are great.

Coleman - Both our cookers are Coleman petrol stoves.  1 Duel Burner and one single.

ECAS - Supplier of Citroen 2cv parts.  The car wouldn't be going if these guys didn't supply me with spare parts.
