I use 6 oz cups to start the seedlings using 100% pro-mix. Then when the tomatoes grow out of those cups I move them into the 16-20 OZ cups purchased from Costco and I use the same mix as tania. I/2 part pro-mix to 1/2 part screened compost. Some how the tomatoes know when they are moved into a larger container and they really take off.
My red cups from Costco need drainage holes and in the past I would drill a hole in the bottom of the cup but if the drill was dull I would not have a nice clean hole. After several damaged cups I have changed my strategy to make drainage holes in 1000 cups. I make a bond fire in the backyard. Heat up a piece of rebar red hot stack up 6 cups (bottoms up) and melt the hole instead of drilling a hole. I have 2 rebar poles red hot and it only takes seconds to make a hole and it comes out clean every time.
