TL;DR: Buy champs with IP to save RP in the Snowdown Shop

Ashe costs 260 RP and the Heartseeker skin costs 975, so buying them together without a discount costs 1235 RP. My Snowdown Shop discount was 70%, meaning Ashe and the skin together cost 370 RP. I knew that Ashe is super cheap in terms of IP and I thought, "What if I bought Ashe with IP first?"

I bought Ashe for 450 IP and the Heartseeker skin for 70% off at 292 RP.

"Well, that makes sense, why make a discussion about it?" Because I am a noob trying to help other noobs that might be on the boards. And I forgot to screenshot the evidence because I didn't think about posting here when I did this last night. [zombie-brand-facepalm]
