I use my local stores a lot, but for online shopping I use
Discount Hobby which is also known online as
Dragglestown.
They have pictures of almost all minis they sell, very speedy shipping, and great customer service. Most of their Reaper Minis are discounted, too. Not sure about the other lines.
I have ordered from them at least three times, and each experience was very positive.
Here are some of the lines they carry:
