Ok, you gotta help me here.
My english sucks and I'd like to know what you think of the grammar of these adverts:

Get rid of old and dusty Loretomes, buy them as ebooks!

Forget stone maps, save your time with CragCrag!

Beat at day's end? Try real magic!

Steroids. 'Cause sometimes potion of healing isn't enough.These are going to be on my page!
And yes, that's the best I can think of

Cheers
