The tissue papers and paper rolls look especially well priced for those that do paper piecing. I picked up on the English language issues just reading the first few lines on the main page. Think I will stay away from mail order but if I lived close would definitely go take a look.
If you are only looking for thread there is an exceptional thread place near where I used to live in NC. It is called Thread Exchange and they do mail order. There website is here:

Love walking into the place and finding the huge spools for just a few dollars and they do carry big name brands, metalics, kevlar, and glow in the dark.
It sits next to a uniform manufacturing plant and supplies them with all the thread they need for their badges and construction. If you go in you can purchase the ends of the spools for less than $1.00. Some of them are barely used but when they change over from one run to another they just throw what they had been using into a big container and start with new spools the next time. I run by there each time I make the trip back to visit old friends. I have no affiliation other than being a very satisfied customer.
