At one point in my herp keeping ventures, i made a chart that lists companies and all their kinds of feeders, their prices, which feeder is cheeaper at which seller, as well as which combination is cheaper. I know... it was very nerdish of me, but at the height of your herp crazed phased, almost everything you do is herp related.
Anyway, I came to a conclusion that the best place to buy crickets online (notice i said ordered online, and local pick-up wasn't considered at the time of my "study" ) is LLLreptile. 1, because they are the cheapest($15.95) shipped. Two, their cricket count is twice that of most places. Reptilefood.com charges about 18 bucks shipped for their crickets, but the number of crickets is half to that of LLLreptile, eventough it is stated to be 1000 crickets.
Reptilefood.com's service is unparalled though. their service is the best of all the companies i have tried. There was once, part of my order was damaged i.e. my shipping box arrived crushed(thus causing some cricket loss). I complained and they immediately replaced the whole order, with mealworms and waxworms too, eventhough those weren't part of the damaged goods. needless to say, i got the better end of the deal. Their shipping packages are excelent too! and oh, you can also schedule when you want your package to arrive, something you can't do with LLLreptile.
Also if you are ordering combos, like some mealworms and some crickets, it is definately cheaper to order from reptilefood.com.
So, to sum it up. i just normally do it this way. If i am ordering a combo, i go to reptilefood.com. And if it is just crikets, I use LLLreptile.
So, if it is just crickets you want lele, My recommendation is LLLreptile. And oh...sorry for the long post.
