Just took advantage of this offer. Been looking for cheap backpacker travel insurance for an 8 month trip. Go Walkabout were one of the cheapest on Money supermarket. Was going to buy it there but then had a look at their site and saw this offer of a free WristVault if you spend over £99.
No good if you just want some insurance for a couple of weeks but good if you want some long term travel insurance as they are cheap anyway for these trips.
