Hi, I'm planning to do a giveaway on one of my blogs, and I came across this plugin called Sumoking Giveaways or something. Anyone who shares the giveaway via the plugin will get extra entries to the giveaway via some special links, so better chances of winning the giveaway. This is a very good incentive for people to share the giveaway. However I look at the price tag of the plugin and I don't think this function is worth $200. It seems simple enough, like everytime you share the giveaway a script generates a unique link under your account or something, much like url shorteners but a little bit different. Am I right? Or is it actually very complex and worth paying up the $200 for?
