Hi Snicker,
I think it would be safe to answer your question with a yes. Although I have yet to find out how good their customer service really is, I sent an inquiry on your behalf :)
They have been online since 2006 and seem like a legit company altogether. They accept safe payment methods and only sell to business owners or resellers.
Here's a related post on the forum (it includes a post from a member who has actual used this supplier):

I would suggest you try to get in touch with them too - so you can ask any questions you have and have it answered directly by them.
Hope this helps a bit :)
