Astro Nautilus skin in My Shop not priced properly!!

Hi... uhmmm. so originally this skin is 1350 in the shop. In the Your Shop it shows the original price as 2230 RP and its discounted at 70% to bring it down to 669 RP. I was planning on getting this skin until i saw the original price was hiked up nearly 900RP from what it is currently in the store. Why is this happening and will i get the price reduced to what it should be? Riot please help me!!!!
