I believe that the digital scrapping world does two things wrong. First, designers as a group give too much stuff away for free. Second, there are too many free tutorials that are excellent and cover the basics and beyond.
Remember what your mother used to say about buying cows when milk is free? When there are lots of freebies out there, it makes it hard for someone who is trying to sell a product to convince a potential customer that their product is worth paying money for. Especially when it isn't any better than the free stuff. Sometimes it's last month's free stuff.
The designers I buy from have very few freebies available and there are no good, free Photoshop reference books. They don't give away the milk, I'm willing to buy a cow. I'll buy on sale, I'll use coupons, but I'll buy. I'll buy because it is more convenient than waiting to find a freebie. I'll buy because I know it will never be a freebie. I'll buy because I saw it in a gallery and fell in love with it. But I don't ever buy because I got a freebie from them.
