Where's the 4* posters in the web coin store?

It's always the same - Honky Tonk, Dusty Rhodes, Stephanie and Shane shards and always the same coins, props and what have you. Regardless of whether you do the free roll, spend, or drop 999 on the mega reroll. Are these ever-so-elusive characters posters even in there? Or is this a case of false advertising?

I'm at the point where I have Charlotte, so I've been rummaging through this store long enough. But spending 999 web coins just produced 2 purple theif, and 3 mega strength. Wtf! Mega reroll is supposed to produce very rare, epic, legendary, and mythic. Yet every time, it's only ever very rare across the board. C'mon now.
