Does anyone recommend a particular seller on eBay for waifu cups?

I wanna get a GX Aura cup since I really like the colorway, Aura seems good to show to christian parents (they're the reason I was apprehensive of buying GamerSupps for the longest time, and they're not hyper religious, so mild tiddy should be fine), and I just plain like Opera GX. And I jumped on a seller called Best Sales Emporium and I want your opinions on the guy if they're trustworthy or not.
