I also found a few other sites outside of SaleHoo that could be worth checking out. Please note we haven't verified these just yet (I have added to our internal list) but I wanted to try and get you a comprehensive selection, hope you don't mind :) We highly recommend that you use a credit card or PayPal for a safe business transaction when you're ready to order.

Make sure you contact them directly in order to get their reseller's pricing which is always better than you will see on their site. When doing this, provide them with the quantity you are ideally looking for, where you want them shipped to, and how often you plan on purchasing - this helps gets the best possible price.
Hope this helps you out and if you need anything further just sing out :)
