Easyjet Mobile site vs Desktop site price difference

Just booked some flights for June on easyjet.com on my phone.

I noticed that for exactly the same criteria the price on Desktop site is £10 cheaper (per return ticket) than using Skyscanner or mobile browser.

All you have to do is go to the setting of mobile browser and tick the box 'Desktop Site' or 'request Desktop site' depending on your browser.

Doesn't sound much but now we paid £36 return instead of £47
