Just got an email…
"Travel Insurance Direct is offering you, your family and friends 10% off the cost of travel insurance for your next holiday."
If your travel insurance is not a lot try looking out for a voucher that gives $5/$10 off the total amount instead.
EDIT: with many thanks to itx (see below), TIDTHANKS will give you $10 off your insurance.
I would be careful using TID. I claimed a lost camera a year ago. The camera was 3 years old and cost $450. They wanted to pay me $60 to replace it. The same camera was selling used on eBay for $130 plus, so it was impossible to replace it for that amount and then also add the cost of the memory card and case.
Granted they do state that items covered will and can be depreciated before payout. But 85% is a little ridiculous. Plus they do not disclose the depreciation formula used. It took a lot of hassle and letters to reach a semi-reasonable payout of $150.
So if your looking at purchasing travel insurance to cover goods, better look elsewhere. I would class TID as health cover only (although thankfully never had to claim for a health related expense).
