These guys are serious about security and have amazing customer support. If you need an SSL certificate or a site seal to assure your buyers about a safe shopping enviroment, you can get it from ControlScan.
Easy to use, professional site builder which supports E-junkie.
We host all our side projects and auxiliary sites at DreamHost (aside from E-junkie.com itself, as that's co-located at a secure datacenter here in Tucson). They provide ample of space and have been as reliable as one could expect. What we love about them is a great trurnaround time for responding to support e-mails and non-canned replies. You can use the code EJDOLLARS while registering with them to get $50 off your order.
Domain Name Registration
We transferred E-junkie.com and related domains to Dotster quite a long time ago (after hearing horror strories about other Registrars), and we plan to stick with them (unless we start a Co-Op style Domain registration service of our own some day).
We use this for text-based live chat on our site. The chat box in your page simply communicates with any Google Talk-compatible instant messaging program at your end, emails a post-chat transcript to you and the chat user for reference and followups, can optionally engage site visitors in chat proactively, and more.
Advanced Post-Checkout Integration
From the developer behind EasyE-junkie -- cartWiz can retrieve your order data to perform many additional functions beyond what E-junkie itself supports natively, including tools to help you manage your business and integration modules for many third-party services.
Free Webmaster Resources
A great resource site for all sorts of free tools like text editors, website authoring software, FTP programs, back utilities and whatnot!
The Webmaster's best friend! :^) Awesome HTML and CSS tutorials from Beginner to Advanced level, along with handy lookup references (say, what's that tag again?). Helps you learn it right the first time according to Web coding standards and best practices (so you don't have to unlearn bad habits and fix things later)!
