That's 2 full months for the price of 1!
On every ad space!
I've only ever done this for my small and medium ads in the past, so those that snatch up the 2 large ads and the 1 banner ad are really getting a great deal, as you'll also be featured in a highlight post and have the options for a giveaway if you'd like.
Just go to my advertise page and click "buy now" on the ad space you want to purchase. You'll then be directed to Passion Fruit to upload your amazing banner and make your payment. That's it! Your add will go up as soon as your payment is clear and remain on the blog for 60 days!
If you have any questions, feel free to email me at jennifromtheblog at gmail dot com and I'd be happy to answer them!
