Buggysnuggle??

Hi all, 

I need to get a footmuff or cosytoes (what is the difference?? I've never been able to figure it out!) for my LO.

I love the Buggysnuggles, but with money being the way it is, they are a bit out of my price range. Does anyone know of a similar cheaper product? Or somewhere I can get a second hand one? I've tried e-bay, but have had no luck. 

Thanks in advance for any help!
