They offer good deals for some items with very affordable prices. I compared them on different sites, this one seems to be the best. I haven't received the goods yet, however I had no difficulty placing the order.
I found PDF Splitter Pro and wanted to automate my invoice processing. The worst part was that our invoices arrived 2-5 in one PDF, each can take 1-4 pages. There was no way to automate that with the regular PDF splitting apps. Coolutils's app didn't do the job either, but they offered a custom version that solved the problem. That was beyond my expectations.
