I recently got a message (through my contact form) from this new milk tea store (from my search they have some 12 stores) in our country wanting to advertise on my blog. I've been blogging for months but I'm fairly new to advertising. So I did some searching on the store and they do exist. The email ad that they used comes with their website (like marketing@nameofmilkstore.com). I checked their website, their twitter, their facebook. Some bloggers were invited to their opening of the store and blog about it. So I do believe this is real.

I really want to accept this offer but I want some advice first from my fellow bloggers. What are your blogging advertisement 101? Do I charge them and how much? My traffic and viewers are like 20-100 or something

Thanks :)
