Ordering online will quickly get expensive. There is little price difference between them. I've used flucker's and premium crickets. Both provided good healthy looking crickets, but I liked the shipping options better with fluker's.

If you only have a few mouths to feed then as weekly trip to the pet store will be way cheaper. I raise my own crickets and there is only a two week window out of the eight to ten week lifespan that they are feeder size for FBT's. Crickets are easy to raise, but if you don't have space in a garage or some sheltered area outside your house, then I don't recommend them. They can get smelly if they don't get enough ventilation. But if you have ten or so cats/dogs in your home you might not notice <<grin>>.
