List Building and Free gifts

Whether through sheer coincidence or a concerted effort, recently I notice several internet marketers offering a pack of products at "cheap price" or even for free. I think it started with the Send US to US (100 products, with many affiliates rallying behind them), then there is the Cody Moya' 200 Master Resell Rights Products (free download). Now there is the Edmund Loh's 41 August Awesome Fun Gifts (free download)

What a massive dose of information over 2 weeks!!

All this in the name of building a list.
