I cant tell you how many sites i've been to over the last year just to snag a file to see if it's something i want to use.
In order to get that script, add-on, etc they want you to pay their VIP price. Most times it's outdated to start with. If you're going to pay for something, it's foolish to bother with most VIP systems.
Granted there are some things that are stupid prices from the devs, and in those cases if you're really hard up for the software i could see MAYBE doing vip. but really, most things aren't that expensive and you get 1 year of updates, don't have to keep pestering the poster to update his 4yr old title with anything newer.
The sad state of afairs is that most of that crap can be found online free.
