What online hobby shop has the best prices?

best prices and best service doesn't usually go together. Usually the service is slower with the "low price leader". It depends on what you are looking for. Most companies who carry the aftermarket stuff usually are strong in one area (aircraft vs ships vs armour). This group can probably help if you can be a little more specific.

Great Models did match a price for some kits at a lower price from another online dealer. You can always ask if they will match a lower price. Just email them with the link of the lower priced item and see what happens....
