I enter all of the EF ones but I haven't won one yet I tend to enter any free contests/giveaways I can, I figure if I enter a lot, I've gotta win one someday! Actually I did win 3 free yoga classes and yoga mat at a local farmer's market, I totally didn't expect it and it was pretty nice, my partner really wanted to enroll but we were too tight on money at the time.
I enter any I come across, as long as I would like the prizes. I didn't enter a recent one because the gifts were non-transferable & included a chicken coop/house, baby chicks, feed for a year, etc from a gardening magazine. I have never won any giveaways until the St Patrick's Day event quiz & an Eden Cooks' quiz. EF will never get rid of me after that! Those are the only times I've ever won anything in my entire life!
I do sometimes but I've never won anything so that probably contributes to the apathy
If it's an item i'm very intrested in i will enter a give away, not only on eden but hosted by other blogs as well. I know my changes of winning are often slim but it's a fun surprise when you win! While i've never won a give away hosted by EF i have won a couple things like a poster, a tape of an artist i really enjoy, and other small things like art and stuff.
