Are you hosting a giveaway? Are you looking for giveaways to enter with the chance to win? I host two giveaway linky lists to which you can post a link to your giveaways so that others can find them.
Whatever your giveaway--
Add it to the linky list at abitosunshine!
Linky List at Ruthi Reads!
Both of my giveaway linky lists are updated weekly (if not more frequently). By requiring that all giveaway submissions include the end date of the event in the title, it is easy for me to keep the lists updated to show only current giveaways for readers to enter.
I advertise these linky lists on a regular basis via Google+, Twitter, and Facebook.
