Now that 5.0 is on live and that we got the grocery store that has this option:

i think that this event:

is utterly outdated, both for the cost of the threads themselves and in the options to take part in it.

My suggestion is, if you want to keep live this event, to cut the cost of advanced threads to 8-12 at most (even with a 40% discount, 38 is a way too high price) and to let us also use coupons to buy them, otherwise this event will be almost wholly deserted.
