Easyjet Tricks - guide discussion

I am looking to fly out on a Saturday to Thursday in October during school holidays but will try the Flexifare trick and book flights a week later which are much cheaper. Does anyone know, if I book Flexifare, do those flights need to be the same days as the real flights I will be changing them to? (Do I have to book Sat-Thur or can I book Thur-Thur as they are cheaper?)
I am aware I need to book the same route. Look forward to some help......

I'm sorry but that Flexi Price seems to be some poor quality joke. Just checking prices for next month to Alicante. ALL OF THEM well over £200. So for the family of 5 it will be something like £1100-1200...
I paid £700 from Ryanair last school holiday.

Surprised this trick is not 1 of the 18 easyJet tricks on money-saving expert's website. It only works for flights starting from abroad.
1) If you're flying a single flight from a non uk airport to any destination with easyJet, first add any flight originating in the uk to the booking, let's say London to Zurich, then add the flight you want to book by clicking add more flights, then click continue and then click the cross in the corner of the London to Zurich flight to remove it and you're remaining flight will have gone down in price by about 15% compared to booking it without this trick.

2) If you're booking a return flight let's say Athens to Manchester one does the trick as follows: if I book
Athens to Manchester 21/12 returning 23/12 it's £315. If you first add Manchester to Athens on 23/12 to the booking and then click add more flights and add Athens to Manchester on the 21/12, the price will go down by £30 to £284. I checked it through to the payment page and it stays at 284. Basically what you're doing here is adding the second flight before the first.
The logic behind this trick is that any easyJet booking where the first booking is a flight starting from the uk, any flights in the same booking that are not starting in the uk, get a 15% discount automatically. In 1) you're adding a uk flight first to get the discount and then removing the uk flight but still getting the discount, in 2) you're actually using both flights just adding the return flight before the outward flight to the booking.

Welcome to MSE Apzm, it's not in the tricks but has been discussed in the forums where more reasons are detailed.

Can you let me know the link to where this deal have been discussed? Thanks

Just booked 4 return flights to Dalaman, Turkey, for the last two weeks of May 2017; including extra legroom both ways for a total of £526 (which includes the credit card fee)! :-)
