I posted this too on StockXpert forum, so foar nobody cleared things up for me. I'll just copy / paste the same message.
Hello all,
Unfortunately I don't have enough time to search the boards to see if this is right so I apologise if it has been discussed over and over again already

I have subscription XL size sales on JIU and StockXpert only. To my knowledge, there should only be maximum L size, for sub sales. Isn't it so?
Anybody having an opinion? Steve?
