Just to offer a few thoughts / clarify a few things regarding kits and download credits:
Because kits are generally large zip files which include many assets and/or templates, we will not be able to offer them for less than 10 download credits, which means that most people will not be able to download them without making a donation. The cost of the storage and transfer for such large files is simply too high to allow us to give them away for free to hundreds/thousands of daily visitors.
That being said, almost every item that is included in a kit will also be made available "for free" individually here on Pixel Scrapper (generally a little while after the kit is uploaded): our intention is not at all to "force" people to donate. Rather, I see the ability to download a whole kit as a "bonus" for people who support the site (and note that kits will always be offered at a "discount" of download credits when compared to the total DC needed to download each item individually).
For those on a tight budget, keep in mind that there is also the chance to win large amounts of download credits by joining one of our challenges.
Also realize that the number of DC required to download items is still very much in flex: we are in the process of analyzing our costs, and determining how much we can offer for free, and still survive. Please be aware that we pay directly for each and every download that goes through our system, regardless of whether someone has donated.
Our intention with this site remains to offer as much as we possibly can for free, to give generously and inspire creativity, and also to try and allow the site to exist financially (and hopefully offer designers reasonable compensation for their designs), through our donation system. If you like the system, then please do donate, but don't feel compelled!
Feel free to offer any thoughts or feedback on the system, or ask for clarifications. As always, your support is very much appreciated!
