I've been to the Ranger warehouse sale three times. The first time was great. I got a lot of inks, re-inkers, etc. The second time I went, it was OK. I went with a few other people, and we got there late, so there wasn't much left. I went this past September, and I was very disappointed. The first 10 people or so came out with 3-4 large bags stuffed with products. That didn't leave much of a selection for everyone else. (I was only about 25th on line, and I got there a half hour before it started.)
What happens is that store owners and people who run large crops practically camp out in front of the warehouse hours before they open their doors and buy up all the "good stuff." Although I did manage to get a few good things, it really wasn't worth the hour + drive, tolls, and gas for me. I don't think I'll be going next year.
