for the champs that have skins on sale. (Exception for Syndra, I don't even own her.)
But I have Unchained Alistar, Vandal Jax, Final Boss Veigar, and Mad Scientist Singed...
On another note; Does anyone know if the Secret Agent MF or Woad Ashe skins have gone on sale yet?
You can find charts that show the last time champions/skins were on sale, and an estimate of when they might come up again. I've got one here;
Woad Ashe was on sale June 27, 2014 and can show up on the sale at any time
Secret Agent MF was on sale February 25, 2014 and could show up soon as well
However, Riot is again releasing monthly schedules, so you can see what will be on sale up to a month and a half in advance. They release it on the front page news;

Neither of those are set for sale between now and the end of August.
