You can probably find them cheaper at a local lumber yard plus not have to pay shipping. Plan on more than 1 per plant if growing indeterminate varieties.

I haven't used them, but would definitely give them a try. I like that they resist decay. Really important is that they come in different lengths although I suggest using the 72 inch. Tomato plants get very tall and require lots of support. I would put one in the ground about 3 inches out from the center stem at the time of planting. Then, tie the stem to the stake at about 1 1/2 foot intervals as the plant grows. You can use garden tape, twist ties, or the new garden clips that are reusable. Don't use anything that will cut into the tomato stem. Even with a great stake, you also need to cage your tomatoes to keep them healthy and from breaking.
Best ever tomato cages are the concrete reinforcement wire. You can buy it in 4 X 8 pieces which is a perfect cage. You just need to connect the sides (we use the pig staples but you can just tie them with wire) and you have a perfect cage that can be used year after year.
We have to put stakes inside to secure the cages against heavy winds, but that isn't always necessary.
I have used cages for many years, and I really don't like them. I am going to all stakes, and I was just wondering if this was a credible supplier. I need about 130 of them.

Store bought cages are only for looks only. home-made cages work great, either from concrete reinforcement wire or pig fence. They can be cut to any size desired or they can be used as a back supports, using thick cords to tie them to the supports. If made correctly they can be spread out or folded up for easy storage. Last year I used the branches I cut from my Confederate Rose Hibiscus and used thick cords as added supports.
I definitely go for the home-made concrete reinforcement wire cages. They last for years, won't blow away if you put a couple of stakes of rebar inside each one and it will eliminate constantly tying them up.
I have been using the same ones since I made them over 10 years ago. I also use them for young trees to keep the deer away and for beans/cukes.
The oak stakes are not expensive but what is the shipping cost? I guess if you have them in the garden for the summer then pull them and store in a dry place, they would resist rot.
I use bamboo for stakes.
