Found this ladder on Argos. Seems like a decent price. Been watching this on Argos site for a few days and pretty certain this was £79.99 (although the website doesnt show it as discounted, just their lowest ever price)
This combination ladder is a super-versatile with 10 positions in one portable package. The compacted length is a convenient 90cm, with a maximum length of 3.38m as an extended ladder. The ladder is easily foldable for convenient transportation and storage, and its easy click-lock system.
Simple click-lock hinge system and compact folded dimensions for easy transportation and storage.
