Offers upon signing in to mylot

I actually keep myself logged into mylot so I don't have to sign in every time that I am coming on here. That said, I would assume that the reason for the offers that you are referring to is because of the fact that mylot has to get its revenue from somewhere and this is the way that they pull their revenue in. It could be frustrating I know, but knowing that without sponsors there would be no earning makes it all worth it to me.
