I agree with the other customers of J Hittles -- very large selection of product types from dozens of different makers, excellent pricing, reasonable shipping, and orders arrived fairly quick.
But it always pays to do your homework and compare. Remember to include shipping costs when you're figuring prices -- some companies charge based on the dollar amount of the order or number of items, others by shipping weight (the most equitable method IMHO).
