In this link http://na.leagueoflegends.com/en/news/store/sales/may-sales-schedule it says arclight vayne should be available on sale in may, but i still haven't seen it and I think the last skins came out today that would on sale this month, Are they just lying?
There is still the 31st of May to look forward too. I made a picture of all the sales they've done this month and the ones they have not. You should see Commando Xin Zhao, Debonair Galio, Heartseeker Varus, and Arclight Vayne for the next sale.
It's great you're looking forward to a skin. I did that for Arcade Miss Fortune. It didn't come out until the end of that sales month too. It was awful waiting for so long. I get the pain of anticipation. Good luck friend.
