So I have a RCQ and i cant find certain card in my LGS and im not ok with TCG player, where can i order high grade passable stuff for the RCQ?

I went to purchase a foil NM [[Solitude]] seeing the market it was right under $40 and at check out they say its in the 70s and the market shows that in some recent sales but it was a small spike then righted itself. I went through with the trade and purchase but the market data seems wonky like someone is trying to raise the price and its messing with the data. Any thoughts?
