flash sale

hi! i just saw that eurostar is doing a flash sale (wished i knew that earlier and i wouldn’t have booked my trips in june & july) but i have to go from paris to london in august and i was wondering if eurostar had already done sales for tickets in august? or should i buy full price

i kind of don’t want to do the same thing as i did for my trips in june & july and spend 135€ instead of 78€ lol
