The package deals usually aren't "deals". They cost much more than if you were to buy the printer (iP1500 or iP3000) from amazon.com or even on eBay as long as it's new and not refurbished. The iP3000 is on sale right now at Amazon for $49.99 after rebate.
I buy my inks and sheets directly from kopykake but sugarcraft.com also sells kopykake brand and ships a lot faster so if you're in a hurry, order there. The price will be about the same and IMO kopykake brand inks and papers are the best quality. Lucks and Photofrost are good brands too and photofrost will sell wholesale and in bulk via their website.
