Wow, you win BIG!!
I have been entering sweeps for about 3 years also and I mostly do the IWG. Sometimes I do the daily , weekly, or 1 time entries. I do the IWG everyday if I am home and have access to the computer. I have won lots of small things, food items mostly(hey it all adds up), some $10 GC., a $50GC and I think the biggest , money wise, was a pair of Brooks running shoes valued at $130. I was pretty happy about that. I am happy about all my winnings actually, it makes me feel good.
That is awesome all the things you have won. I think it is cool to know that real people actually win!! I wish you continued success.
