Ever since it launched in the UK in 2005 online deals publisher Travelzoo has claimed its deals undergo the most rigorous independent testing to make sure they are what they seem.
So this week a select trio of trade journos, Travolution included, was invited down to the firm's Covent Garden offices to see for themselves the process.
We sat through the weekly Monday Top 20 meeting, the first of the week when potential deals and leads are discussed and scrutinised for inclusion in Wednesday's deals alert.
It's easy to be cynical and to expect that, in truth, as long as you're prepared to pay your deal gets in the list, but Monday's exercise was designed to demonstrate this is not the case.
The London team consists of 10 "producers", mainly ex-journalists we were told, with, judging by the array of accents, plenty of firsthand experience of international travel.
Also patched into a conference call, reminiscent of the judging in the Eurovision Song Contest, were producers in Manchester and Switzerland.
"Come in Switzerland, this is London calling."
A long list of deals harvested from the weekend papers were in front of them each to be discussed debated and either discarded or given the Travelzoo seal of approval.
One cruise deal hanging in the balance was put to the vote and lost out - a little too niche, particularly compared to a last minute Med cruise deal that was given the nod.
At first glance trying to verify if a particular deal is the best in the market would appear to be an almost impossible task with all the options available.
But with enough people, enough time and armed with data on previous deals featured it appears it is possible to give a weekly assessment of the merits of a particular deal.
So, on Monday we saw a Croatia holiday deal left out because, when the £3 protection fee was added it wasn't that competitive after all.
A Prague short break costing just over £100 needed more research because, with cheap Prague flights earlier considered good enough to make the list, it might be possible to package up cheaper.
A Tunisia break advertised by a well known Online Travel Agent was discovered to be not as cheap as a comparable trip offered by a well known high street travel agent.
It was decided to contact the latter directly to give them the good news about how good a deal they were offering, and to see if they wanted to get it on the Top 20 list.
Price, clearly, is a key consideration but not the be all and end all.
To make the Top 20 the deal just has to be considered to be market leading, and it also helps if it's eye-catching.
Flight deals from a new eastern Europe airline made the cut, not just because a new airline is something of a novelty these days but departure and destination airports were unusual.
Each week the Top 20 is made up of paid-for advertisements, which Travelzoo says go through the same rigorous testing as the free ads that make up the list.
Travelzoo is also able to segment its subscriber database, so certain slots in the Top 20 can have more than one deal against them.
Producers admit it can be hard to find enough fantastic deals each week and maintain Travelzoo's Top 20 reputation for only highlighting the very best offers.
But still a deal could be knocked back if records of subscriber ratings of previous deals (marked out of 6) are not good enough or even a little local knowledge casts doubt on an advertisers' claim.
We were told a UK hotel was once visited in person by a Travelzoo researcher before an offer was verified and on Monday the inside knowledge of a native New Yorker helped one deal through.
For Travelzoo producing a diverse range of offers for the Top 20 is just as important as making sure those deals exist.
On Monday everything from £1,000 long-haul holidays to domestic coach deals priced in pennies came under scrutiny.
It's travel's very own game of Deal or No Deal?
10 tips for getting your deal on Travelzoo's Top 20
1. Market test your offer - make sure your deal beats those being promoted by all your main rivals
2. There's no point lying -Travelzoo's researchers and test bookers claim they will weed out any spurious deals
3. Don't make your deal too last minute and make sure you have sufficient stock to make it a viable contender for Travelzoo's one million UK subscribers
4. Iron out any glitches in your website - Travelzoo test bookers based in Germany claim to have found 18,000 on European travel websites last year alone
5. Include something eye-catching, or "newsworthy" like a free excursion, meals or transfers
6. Be prepared to argue your case - you could be called directly by a Travelzoo researcher about concerns about your hotel
7. Keep an eye on your Tripadvisor reviews - Travelzoo does and factors these in
8. If you're an agent know your product because any concerns that can't be answered might count against you
9. If you can't be the cheapest offer something unusual like a new destination, new flight or hotel
10. Try to make sure there are plenty of departure dates - a cheap deal to the Caribbean in the middle of hurricane season isn't likely to make it
